Installation guide · free to copy

What to install before the Wikilook AI Workshop

Everything you need installed, in the order to do it, with the Windows steps and the macOS ones beside each other. All of it is free to read and free to follow — none of it is a secret, and most of it is on YouTube somewhere. What is not free is the afternoon where somebody sits next to you while it goes wrong, and the material we hand out there.

A.1What each format covers

Same method, three lengths. The badges on every chapter below say which formats include it; the filter in the bar hides the rest.

STANDARD ( 4h )

4 hours · 30–31 Oct, Bratislava

Six hands-on blocks with one break. Inbox, invoices and the family budget, ending with an app on your phone.

what you leave with

  • Everything in MINI
  • Two real Excel workbooks: family finance, and company accounting with VAT
  • A year of invoices renamed, filed, recorded and reconciled against the bank
  • A closing pack ready for your accountant
  • A four-tab app on your own phone, fed by your own spreadsheet
  • A short vertical video, edited over MCP

Read this before you install anything

You are about to give an AI assistant access to a computer account, a mailbox and a Drive. It can create, rename, move and DELETE files in what it is given. It asks before anything destructive, and it is right most of the time — but it is not perfect, and neither are you at four in the afternoon.

WIKILOOK and NODE MORAVA take no responsibility for data you lose this way: files deleted, mail archived, a spreadsheet overwritten, a folder reorganised into something you cannot find. That is not us being careless with your work. It is why the next two chapters ask you to make a separate Windows account and a separate Google account, and to put nothing in them you could not lose.

Follow those two chapters and the worst case is an afternoon of practice files. Skip them and the worst case is your real desktop. Both are your choice; only one of them is ours to repair.

Give the AI its own environment, not yours

Do not rebuild your life with AI in the first week. The temptation on day one is to point it at everything you own and let it tidy up. Resist that for a month.

Work on COPIES. Bring material over from your old machine into the workshop account — a folder of invoices, a few photographs, one spreadsheet — and organise it there. Your current setup stays exactly as it is, which makes it the backup, and a backup you have not touched is the only kind that is certainly intact.

Later, when everything is genuinely backed up and you have seen the method work on copies for a few weeks, you can let Claude reorganise the old machine. That is a decision for a calm afternoon, not for the first evening.

For now treat the old laptop as a closed chapter. The new account is where the new way of working happens, and it starts empty on purpose.

And if you are properly committed: buy a second laptop, the fastest CPU you can justify, and hand that one to the AI completely. Your own machine stays yours, and the assistant never learns everything about you. Expensive, and the cleanest separation there is.

Quick start · one page

0Before the Wikilook AI Workshop — the 30-minute minimum

Three accounts and one app. That is all you must arrive with. Everything else we do together, and the long version of this is the full installation guide.

  1. 0110 min

    A separate Windows account

    Settings → Accounts → Other users → Add account → “I don't have this person's sign-in information” → “Add a user without a Microsoft account”. No Microsoft account needed. Then Change account type → Administrator, so the installs do not stall.

    Everything the AI touches lives in this account, so a mistake can only reach practice files. Demote or delete it after the day.

  2. 025 min

    A new Google account

    accounts.google.com/signup, something like yourname.ai@gmail.com. Turn on 2-Step Verification straight away.

    We connect Gmail and Drive to it. Use a NEW one and put only practice material in it — share real files in from your main Drive when you need them.

  3. 035 min

    Claude, on a paid plan

    claude.ai → sign up with that Google account → Settings → Plans → Pro. Add the card now, not in the room.

    The free plan has the chat window and none of the tools. Cancel after the workshop and the unused part comes back.

  4. 045 min

    The Claude desktop app

    claude.ai/download, install, sign in with the same account.

    This is what holds the Gmail and Drive connectors.

Bring: A personal laptop, not a locked work machine. A phone with Expo Go if you are coming to STANDARD or FULL.

Will it run on your machine?

Windows
Windows 11Supported. This is what the guide is written against.
Windows 10 (64-bit, 22H2)Works. Older builds of 10 may refuse the Claude app.

01

Back up your computer first

MINISTANDARDFULL

Before anything else, and before you come to the AI Workshop: make a backup of your machine onto an external drive. Not a copy of your documents folder — a real image of the disk, made by software that can put it back. If this is the only thing you take from the day, the day already paid for itself. Most people have not done it, know they have not done it, and have been meaning to for two years. Consider this the workshop forcing your hand.

WindowsmacOS
1

Get an external drive bigger than the used space on your laptop. A 1 TB USB disk costs less than the AI Workshop and you will reuse it for years.

same as Windows
2

Install Hasleo Backup Suite Free from the link above. It is free for personal use, it makes full disk images, and it can restore to a machine that will not boot — which is the only test of a backup that matters.

macOS needs nothing installed: System Settings → General → Time Machine → Add Backup Disk.

3

Run a FULL system backup, not a file backup. In Hasleo: System Backup, pick the external drive, start it. It takes an hour or two; start it in the evening and go away.

Time Machine's first run takes about as long. Leave it plugged in and let it finish.

4

Make the recovery media while you are there: Hasleo → Tools → Create Emergency Disk, onto a USB stick. A backup you cannot boot to restore is a backup you do not have.

macOS recovery is built in — hold Command-R at startup. Nothing to prepare.

5

Write down where the drive is and when you made it. Then disconnect it. A backup drive left plugged in is a drive that gets encrypted along with everything else.

same as Windows
6

Check it worked — browse inside the backup you just made: Hasleo → Tools → Explore Image, open the image on the external drive, and look for your own documents in it. A backup you have not opened is a guess.

Time Machine → Browse Time Machine Backups, step back to last night, and open any folder of your own.

about 45 minutes

02

A separate Windows account, for your own safety

MINISTANDARDFULL

Claude Code can read and write files, and it asks before anything risky. The cheapest way to make that question easy to answer is to give it its own user account with nothing of yours in it — no OneDrive, no work mail, no tax folder. Then the worst a mistake can reach is a folder of practice files. People who skip this run the AI Workshop against their real desktop, and that is their risk to take, not ours to repair.

Recommended — maximum protection

  • A separate local account, used for the AI Workshop and nothing else. Claude Code only ever sees that account's files, so the worst a wrong answer to a permission prompt can reach is a folder of practice material.
  • Administrator during the day so installs do not stall; Standard or deleted afterwards. Five minutes to set up.
  • This is the recommended route and the rest of the guide assumes it.

If you accept the risk

  • Working in your everyday account is faster and it is what most people will do. It also means an afternoon of experiments is happening next to your documents, your photos and your accounts.
  • If you do it anyway: make sure a backup exists that you have actually restored from once, keep all practice work inside one new folder, and read every permission prompt instead of clicking through it.
  • Your call. Not ours to repair — see the note at the top of this page.
WindowsmacOS
1

You do NOT need a Microsoft account for this. Make a plain local account: Settings → Accounts → Other users → Add account → “I don't have this person's sign-in information” → “Add a user without a Microsoft account”.

System Settings → Users & Groups → Add Account. A local account, not an Apple ID.

2

Name it something you will recognise — ai-workshop will do. Give it a password you will remember for one day.

same as Windows
3

Make it an ADMINISTRATOR for the AI Workshop. Windows: on the same screen, Change account type → Administrator. Installing Node, Git and the Claude app all need it, and a session that stalls on a password prompt we cannot answer costs the whole room ten minutes.

macOS: tick “Allow this user to administer this computer”.

4

Sign in to the new account once, so Windows finishes setting it up before the AI Workshop rather than during it.

same as Windows
5

Do every remaining step in this guide while signed in to that account.

same as Windows
6

AFTER THE AI WORKSHOP, take the rights away again: Change account type → Standard, or delete the account altogether. Administrator was for the installing, not for keeping. Deleting the account deletes its files with it, so move anything you want to keep first — and if you pushed your work to GitHub as chapter 06 says, it is already safe.

same as Windows
7

Check it worked — sign out, sign in as the new account, and try to open your own Documents folder. You should be refused. If you can read your own files from the workshop account, it is not separate and the chapter has not done its job.

Log out and back in as the new user, then open Finder → Go → Home. You should see an empty home folder, not yours.

about 15 minutes

03

A Google account you are willing to connect

MINISTANDARDFULL

You need an e-mail address to register with Claude, and later we connect Gmail, Calendar and Drive so the AI can actually do the invoice work. Understand what that means: once connected, Claude can read that mailbox and read, write, rename and delete in that Drive. Whatever you put in the account, it can touch. So make a NEW Google account for the AI Workshop and put only practice material in it.

Recommended — maximum protection

  • Make a new Google account, used for nothing else. Then the connectors reach exactly the folder of practice files you chose and nothing more — not your contracts, not six years of mail.
  • Need to work on something real? SHARE it into the AI Workshop account from your main one, one file or one folder at a time, from Drive's own Share button. You keep the original, you can un-share it in one click, and the AI only ever sees the copy you pointed at.
  • This is the recommended route and it costs five minutes.

If you accept the risk

  • Connecting your everyday Google account works, and it is faster. It also means an afternoon of experiments is happening inside your real mail and your real Drive.
  • If you do it anyway: check that Drive has a backup you trust, keep the practice work in one new folder, and disconnect the connectors when the day ends.
  • Your call. Not ours to repair — see the note at the top of this page.
WindowsmacOS
1

Open accounts.google.com/signup in the new Windows account. Create the address — something like yourname.ai@gmail.com.

same as Windows
2

Turn on two-step verification straight away: myaccount.google.com → Security → 2-Step Verification. You will be connecting this account to software; protect it now, not later.

same as Windows
3

Put the practice material in: send two or three real invoice PDFs from your main address, or share them in from your main Drive, or use our demo pack and send nothing at all.

same as Windows
4

Put 10–20 photos in Drive, in one folder, for the video block. Family photos are fine; see the note on faces in the safety chapter.

same as Windows
5

Keep the account afterwards or delete it. If you keep it, it stays a useful sandbox: anything you want to try on real data gets shared in, tried, and un-shared.

same as Windows
6

Check it worked — open gmail.com in a private browser window and sign in with the new account. An empty inbox and no access to your real mail is the correct result.

same as Windows

about 15 minutes

04

A Claude account, and a paid plan

MINISTANDARDFULL

The free plan cannot do what we do. Claude Code and Claude Design need at least Pro, and without them there is no invoice pipeline, no workbook and no app. Pro is billed monthly, so you can cancel after the AI Workshop and get the unused part of the fee back.

WindowsmacOS
1

Go to claude.ai and sign up with the Google account from the previous chapter.

same as Windows
2

Upgrade to Pro: your initials, bottom left → Settings → Plans. Max only matters if you intend to work hard after the AI Workshop; Pro is enough for the day.

same as Windows
3

Add the card now, in your own time. Doing it in the room costs everybody ten minutes.

same as Windows
4

Sign in once in a browser and send one message, so you know the account works.

same as Windows
5

Check it worked — claude.ai → your initials, bottom left → Settings. The plan line says Pro or Max. If it still says Free, the payment did not go through and the workshop will hit the limit in twenty minutes.

same as Windows

about 10 minutes

05

The Claude desktop app

MINISTANDARDFULL

The browser is fine for chatting. The desktop app is what holds the connectors — Gmail, Drive, Calendar — and it is where the first half of the day happens.

WindowsmacOS
1

Download from claude.ai/download. Take the Windows installer.

Take the macOS build; it is a normal .dmg, drag it to Applications.

2

Install and sign in with the same account.

same as Windows
3

Check Settings → Connectors exists and is empty for now. That is the shelf we fill in a later chapter.

same as Windows
4

Check it worked — the app opens from the Start menu, not from a browser tab, and shows your own name. If it asks you to sign in again every time you open it, you installed it as one Windows account and are running it as another.

The app is in Applications and opens from Spotlight. Same test: it knows who you are the second time.

about 10 minutes

06

Claude Code in PowerShell

MINISTANDARDFULL

This is the one that does real work: an assistant that lives in a folder, reads and writes files there, runs commands, and asks before anything it cannot undo. On Windows it runs in PowerShell. Install it in the clean account, not your main one. You do NOT need Node.js for this. The installer below brings everything with it in one go — Node is only needed for the npm route in step 3, which is the fallback nobody should need.

WindowsmacOS
1

ONE LINE, AND IT IS DONE. Open PowerShell (not the old Command Prompt) and paste:

winget install Anthropic.ClaudeCode

That is the installer route: winget is built into Windows 11 and fetches a signed package. Nothing else in this chapter is needed if it works — skip to step 4.

macOS: `brew install --cask claude-code`, or the script in step 2.

2

No winget, or it failed? The official one-liner installs the same thing:

irm https://claude.ai/install.ps1 | iex

It downloads a script from claude.ai and runs it — `irm` fetches, `iex` executes. It shows no progress while it works, so leave the window open. You are trusting Anthropic's domain with that line, which is the same trust the app itself needs; if that is not a trade you want, use step 3 instead.

macOS and Linux:

curl -fsSL https://claude.ai/install.sh | bash
3

The long way, via npm — only if the two above did not work, and the ONLY one that needs Node.js. Install Node.js LTS from nodejs.org/en/download (the Windows Installer .msi, 64-bit, default options), reopen PowerShell, then:

node --version
npm --version
npm install -g @anthropic-ai/claude-code

Same three commands. If npm complains about permissions, fix the npm prefix rather than reaching for sudo.

4

Check it:

claude --version

If PowerShell says the command is not recognised, close every PowerShell window and open a new one — the PATH is read at start.

same as Windows
5

Make a folder to work in and start it there:

mkdir ai-workshop
cd ai-workshop
claude

First run asks you to log in; it opens a browser and comes back.

same as Windows
6

Say hello, then ask it what files are in the folder. When it asks permission, read the question before answering yes. That habit is most of the safety.

same as Windows
7

Check it worked — type claude --version in PowerShell. A version number means it is installed. “not recognized” means the terminal has not read the new PATH yet: close it, open a new one, try again.

Same command in Terminal, same answer.

about 25 minutes

Handed out in the room

The briefing patterns

Six shapes of instruction that get a usable answer first time, written out with the wrong version beside the right one.

The one that matters most: say what the result is and how you will check it, in the same sentence. Everything else is a variation.

Includes the sentence I use to make it stop guessing, and the one that makes it tell me what it is unsure about.

07

Git, GitHub, and somewhere for the work to survive

MINISTANDARDFULL

Everything you build in the AI Workshop should still exist next month. GitHub is where a copy lives: free, versioned, and reachable from the terminal and from the web. Claude Code can commit and push for you, so you do not have to learn Git properly today — but knowing what a commit is will not hurt.

WindowsmacOS
1

Install Git for Windows from git-scm.com. Default options are right. This also gives you the credential helper that stops GitHub asking for a password every time.

macOS: run `git --version` once and accept the Xcode command line tools prompt, or `brew install git`.

2

Create a free account at github.com with the workshop Google address.

same as Windows
3

Turn on two-factor authentication. GitHub requires it for contributors and you will hit the wall later if you skip it.

same as Windows
4

Tell Git who you are, in PowerShell:

git config --global user.name "Your Name"
git config --global user.email "you@example.com"
same as Windows
5

In the workshop folder, ask Claude Code to create a repository and push it. It will walk you through the browser login the first time. After that, “save this to GitHub” is one sentence.

same as Windows
6

Check it worked — git --version answers with a number, and your repository page on github.com shows at least one commit with today's date on it. A repository with no commits is a folder with extra steps.

same as Windows

about 20 minutes

08

Connectors: Gmail, Drive and Sheets

MINISTANDARDFULL

MCP is the USB port for AI. A connector gives Claude access to somewhere — your mail, your Drive, a spreadsheet — and every one you add is a thing it can then do for you. We connect three, and we do it together in the room, because this is the step where a wrong click matters most.

WindowsmacOS
1

In the Claude desktop app: Settings → Connectors → Browse connectors. Add Gmail, Google Drive and Google Sheets.

same as Windows
2

Each one opens a Google consent screen. Read it. Grant it to the WORKSHOP Google account, never your business one.

same as Windows
3

Ask Claude to find invoice attachments from the last three months. If it lists them, the connector works.

same as Windows
4

Disconnect anything you are not using when the day is over: same screen, Disconnect. A connector you forgot about is a door you left open.

same as Windows
5

Check it worked — ask Claude: list the subjects of my last three e-mails. Real subjects mean the connector works. An offer to help you set up e-mail means it does not, and the consent went to a different Google account.

same as Windows

about 20 minutes

Handed out in the room

The invoice pipeline, end to end

Collect, read, rename, file, record, reconcile, flag what is missing — the seven steps, the naming scheme, and the prompt for each one.

The reconciliation rule that catches a payment without an invoice, which is the thing your accountant actually wants from you.

What to hand the accountant at the end of the year, and what to keep.

09

The caveman plugin, and why you would want it

MINISTANDARDFULL

Every word the model writes costs you usage. caveman is a plugin that makes Claude Code answer in compressed, telegraphic English with all the technical substance and none of the padding. On a long working session it is the difference between hitting your limit at lunch and not thinking about it.

WindowsmacOS
1

In Claude Code, run:

/plugin

and install the caveman plugin from the marketplace listing.

same as Windows
2

Turn it on with `/caveman full`, off with `/caveman off`. Try one question each way and compare the length.

same as Windows
3

Decide which you prefer. Some people find it abrupt; the point is that you choose, not that you must.

same as Windows
4

Check it worked — type /caveman full in Claude Code and ask anything. The answer comes back short. /caveman off puts it back to normal.

same as Windows

about 10 minutes

10

Somewhere to keep tasks — and how I see what you built

MINISTANDARDFULL

Two reasons for this one. You get a place to keep what you are doing, and we get a way to see what you actually finished, so the help after the AI Workshop is about your work rather than about a screenshot. All the options below have a free tier that is enough.

WindowsmacOS
1

Pick one from the box on the right and create a free account.

same as Windows
2

Create a project called ai-workshop and three tasks in it: install, invoices, app.

same as Windows
3

Connect it to Claude if it has a connector; otherwise we drive it from the browser. Either way, you end the day with a written list of what works and what is next.

same as Windows

about 15 minutes

Handed out in the room

The two workbooks

The family finance workbook and the small-company accounting workbook: sheets, formulas, the dropdowns, the dashboard.

Written as a specification you hand to Claude, not as a file you copy — so it builds yours, with your categories, in your language.

The three numbers to verify by hand, and why those three.

11

Obsidian, your own YAML, and a naming style you keep

MINISTANDARDFULL

The reason most people's AI work disappears is not the model. It is that the output lands in a chat window and nobody can find it a week later. Obsidian is a folder of Markdown files with a good reader on top: no database, no lock-in, and Claude Code can read and write it directly because it is just files. We spend the time on two decisions — what goes in the front matter, and how a filename is built — because those two are what make a pile of notes searchable.

WindowsmacOS
1

Install Obsidian from obsidian.md. Free for personal use, no account needed.

same as Windows
2

Create a vault INSIDE the workshop folder, so Claude Code and Obsidian are looking at the same files.

same as Windows
3

Decide your front matter together with me. A starting point that has survived here:

---
title: What this is
kind: note | guide | register | task
status: draft | active | done
created: 2026-10-16
tags: [AI Workshop, invoices]
---
same as Windows
4

Decide your filename grammar. Mine separates the human part from the machine part, and it is the only reason I can still find something written two years ago. Yours can be simpler — it has to be YOURS and it has to never change.

same as Windows
5

Write one note in the style, then ask Claude Code to write the next three. Check that it followed the rule. That check is the skill.

same as Windows
6

Check it worked — write one note, close Obsidian, and find that same note as a .md file in the folder on your disk. If you cannot find it on disk, the vault is not where you think it is, and that matters the day you want the AI to read it.

same as Windows

about 25 minutes

12

Video, and the one tool we have not fixed yet

MINISTANDARDFULL

The video block is the one everybody asks for and the one with the least settled answer: the services change every few months and the cheapest good one today may not be the cheapest good one on the day. So this chapter is deliberately short, and the final choice comes in the pre-flight e-mail 48 hours before.

WindowsmacOS
1

Create a Google AI Studio account at aistudio.google.com with the workshop Google address. Free tier, no card.

same as Windows
2

Get an API key there and keep it somewhere safe. Do NOT paste it into a chat window, ours or anybody else's.

same as Windows
3

Install nothing else yet. The video MCP we use will be named in the pre-flight mail, and it takes two minutes to add on the day.

same as Windows
4

Have your photo folder ready in Drive. That is the input.

same as Windows

about 10 minutes

13

The competition, and why we still teach Claude

MINISTANDARDFULL

I am not going to pretend there is one tool. You should see the others, because knowing where a tool stops is most of knowing how to use it. Create a free Lovable account before the AI Workshop and build one toy page in it — ten minutes, and the comparison makes the rest of the day make sense. The ranking below is my judgement from using them, not a benchmark, and it is dated.

WindowsmacOS
1

Sign up free at lovable.dev and generate one small page from a sentence. Notice how fast it is and where it stops.

same as Windows
2

Do not install the rest. Read the box, so you know what exists.

same as Windows
3

Bring the question you could not answer with Lovable. That is usually the thing worth learning.

same as Windows

about 15 minutes

Handed out in the room

The master skill for content

The five-stage workflow that turns one topic into a content plan, a post, an article, a presentation with speaker notes, a lead magnet and a landing page.

How the stages are joined so it pauses and asks before continuing, instead of producing forty pages nobody asked for.

FULL only.

Handed out in the room

The comparison we actually use when a client asks

Where each one earns its money, where it quietly costs you a week, and the two questions that decide between them for a small business.

Handed out at the AI Workshop.

14

Other services — read, do not install

MINISTANDARDFULL

A short list of what else exists in the stack we run, so you know the names when they come up. None of these are needed for the AI Workshop and installing them now will only slow you down.

WindowsmacOS
1

Google AI Studio and Gemini — the free tier is generous and Gemini is strong at video and long documents. Account only.

2

Supabase — a Postgres database with an API in front, free tier. This is where a toy app grows up.

3

n8n — workflow automation you can self-host. What you reach for when the automation should run without you.

same as Windows
4

Docker — how all of the above run on one machine without fighting each other.

same as Windows
5

Expo — how the phone app in the AI Workshop gets onto your phone. You install only the Expo Go app; the rest is handled.

same as Windows

about 5 minutes

15

Extra: Expo Go, so the app reaches your own phone

extraMINISTANDARDFULL

Everything above has to work before the AI Workshop starts. This one does not: it is five minutes, it only matters in the block where an app goes onto a phone, and if you run out of evening you can do it in the room during the first break. Expo Go runs the app you build on your own phone without publishing anything, without an Apple developer account and without a cable. Claude writes the app on the laptop, your phone scans a code, and it is running — on your phone, with your numbers in it.

WindowsmacOS
1

Install Expo Go from the store link above. It is free and it does not need an account for what we do.

Same app, same store listing.

2

Put the phone on the SAME Wi-Fi as the laptop. This is the one thing that most setups get wrong: a phone on mobile data cannot see a laptop on Wi-Fi, and the code will scan and then hang.

same as Windows
3

That is the whole setup. On the day, Claude starts the app with `npx expo start` and a QR code appears in PowerShell.

same as Windows
4

Android: open Expo Go and use its own scanner.

iPhone: use the Camera app, not Expo Go — Apple does not allow the in-app scanner, and the Camera offers to open Expo Go for you.

same as Windows
5

If the venue's Wi-Fi blocks devices from seeing each other, which guest networks often do, we start it with `npx expo start --tunnel` instead and it goes out over the internet. Slower, always works, nothing for you to prepare.

same as Windows
6

Check it worked — with the laptop serving the project, Expo Go on the phone lists it, and opening it shows your own screen rather than the Expo example. Both devices have to be on the same Wi-Fi.

same as Windows

about 10 minutes

16

When it will not install

MINISTANDARDFULL

Eight things go wrong, and these are them. Read the error line before you read anything else: every one of these announces itself in words, and the words are in the list below. If none of it helps, stop. Do not uninstall everything and start again — write to us with the exact line and come to the room with the machine as it is.

WindowsmacOS
1

“unable to get local issuer certificate”, from pip, npm or git. Your antivirus is opening every secure connection to inspect it, and the tool does not know the certificate it signs them with. Avast, AVG, Kaspersky and ESET all do it. Either turn HTTPS scanning off while you install — Avast: Menu → Settings → Protection → Core Shields → Web Shield → uncheck Enable HTTPS scanning — or export the antivirus root certificate and point the tool at it.

Same message, usually a company device-management profile instead of an antivirus. System Settings → General → VPN & Device Management shows whether one is installed.

“running scripts is disabled on this system”, when you start anything in PowerShell. Windows blocks scripts for a new account. Run: Set-ExecutionPolicy -Scope CurrentUser RemoteSigned, answer Y, and start the command again.

macOS has no equivalent block. If a command will not run, it is a missing execute bit: chmod +x the file.

3

“claude is not recognized”, or command not found, right after the install succeeded. The terminal reads its PATH once when it opens. Close it, open a new one, and check node -v and npm -v answer with version numbers before you try again.

Same cause and same fix. If a new Terminal still cannot find it, open ~/.zshrc and check the PATH line the installer added.

Claude Code starts but says it cannot see your files. You are in the wrong folder. Run pwd, compare it with where the work actually is, and cd into the project folder before you start Claude Code. It reads the folder you started it in, and nothing above it.

The connector says connected and Claude still cannot read your mail. The browser is signed in to more than one Google account, and the consent went to the wrong one. Sign out of all of them, sign in only with the account from chapter 3, and connect again.

An installer asks for an administrator password you do not have. The workshop account is a standard user. Go back to the account chapter, make it an administrator for the day, install, and take the right off again afterwards.

System Settings → Users & Groups → the account → Allow this user to administer this computer.

Everything is slow, the fan is loud, the browser stops answering. It is memory, not the AI. Close every Chrome window except the one you need, close Teams and Outlook, and read “Will it run on your machine?” again. Eight gigabytes works; eight gigabytes with forty tabs does not.

Nothing above helps and the workshop is tomorrow. Write to info@wikilook.com with the last twenty lines of the terminal, what you typed, and which chapter you were on. We answer the same day, and you come to the room either way — a machine that will not install is a thing we can fix in person in ten minutes.

Closing the door when the workshop is over

MINISTANDARDFULL

This manual spent nine chapters handing out access: a Google account connected to an AI, a machine account that can install software, a repository on the internet, a paid plan. A manual that shows how to open all of that and not how to close it again is leaving your door open and calling it a feature. So: the evening after the workshop, go through this list. Decide what you keep on purpose, and take the rest back. It takes twenty minutes.

WindowsmacOS
1

Disconnect the connectors first, because they are the ones with reach: claude.ai → Settings → Connectors, then Disconnect on Gmail, Drive and Calendar. Then check the other side at myaccount.google.com → Security → Your connections to third-party apps, and remove anything you do not recognise.

same as Windows
2

If you made a Google account only for the day and will not use it again, delete it: myaccount.google.com → Data & privacy → Delete your Google Account. If you would rather keep it, keep it — it costs nothing and it is a clean place to try things next time.

same as Windows
3

Take the administrator right back off the workshop account: Settings → Accounts → Other users → the account → Change account type → Standard user. Keep the account itself. That is where the practice files live, and a standard account can still run everything you built.

System Settings → Users & Groups → the account, and turn off Allow this user to administer this computer.

4

Delete any API key you created. A key in a file on your disk is a key that works for whoever reads that file, and it keeps working until you revoke it at the console that issued it. If you are not sure whether you made one, search your project folder for the word KEY.

same as Windows
5

Look at the repository, not just at the folder. If anything real ended up in it — a client name, an invoice, a password — make the repository private or delete it, and check the history rather than the current files: a commit remembers what you removed afterwards.

same as Windows
6

Decide about the Claude plan on purpose. If you will use it weekly, keep it; if you took it for one afternoon, cancel before the renewal date. Your chats stay readable on the free tier, so cancelling loses the capacity, not the work.

same as Windows
7

Write down what you kept, in one line, somewhere you will find it: which account, which repository, which plan renews when. Six months from now this is the difference between a system you own and a subscription you forgot about.

What you get, and which of it is free. The rule is simple: a setup is free because anybody can learn it from a video, and the material that took years to get right is handed out to the people in the room.

A.3What actually happened, in six months of this

Has Claude ever destroyed anything of mine? Not so far — and that is not luck. It works here under rules that are strict, and the rest of this appendix is what those rules bought.

For completeness: the opening of this guide is a warning, so the end of it should say what the warning is worth in practice.

I have run WIKILOOK on this way of working for six months, with Claude in full control of the folders it was given. In that time it deleted nothing I wanted and lost nothing I needed. Work did go missing temporarily — a file moved somewhere unexpected, a version replaced by a newer one — and every single time it came back out of Git, because everything lives in a repository. That is the practice this AI Workshop teaches, and this is what it is for.

The honest other half: files HAVE been lost around here, and the cause was people rather than the AI — me handing something over, somebody tidying, a copy made in the wrong direction. Nothing important of mine has ever been lost, and the reason is not luck. It is that the backup discipline is strict and was in place first.

So the two sentences that matter are not in tension. The assistant is reliable, and you should still arrange things so that it does not have to be. Back up before you start, work on copies, put the work in Git, and then let it do its job properly instead of hovering over it.

None of this is a promise about your machine. It is one person's record, on one setup, with the precautions this guide spends its first three chapters on.

A.4Take it with you

Every file holds the chapters for that length and nothing else, so a MINI reader is not handed an afternoon they are not attending. All of them are generated from one source, so none is a stale copy of another.
