Install on Claude Code (desktop app)

The Claude Code desktop app is the full production studio: research, copy, ad creative, image and video generation, and complete landing-page builds. Setting it up the first time takes about 15 minutes, and you only do it once.

You will paste a couple of short commands

On the desktop app you talk to Claude in a prompt box, and two of the setup steps are short commands you paste in exactly as shown. There is nothing to “code,” and you can copy each one with a click.

Before you start

You’ll need:

• A Mac or Windows computer.
• Your Claude login (the same account you already use for Claude).
• A free GitHub account. The toolkit is private, so GitHub is how access is controlled.
• About 15 minutes.

Step 1: Get access to the toolkit

The toolkit lives in a private repository, so someone has to let you in first.

1. If you don’t have a GitHub account, create a free one at github.com.
2. Send your GitHub username to whoever manages the toolkit (your admin).
3. They add you to the unicorn-marketers/um-toolkit repository. GitHub emails you an invitation: open it and click Accept invitation.

Where’s my GitHub username?

It’s the name in the top-right profile menu on github.com, and it’s in your profile address (github.com/your-username).

Step 2: Install the Claude Code desktop app

1. Download the app from the official download page: claude.com/claude-code.
2. Install it like any other app, then open it.
3. Sign in with your Claude account.

You should see the Claude Code home screen with a prompt bar at the bottom — that prompt bar is where every command in this guide gets pasted.

Step 3: Sign your computer in to GitHub (one time)

The toolkit lives in a private repo, so your computer has to prove it’s allowed in. Accepting the invitation (Step 1) grants you access; this step gives the app on your machine the credentials to use it. Skipping it is the single most common reason the next step fails with “can’t reach the repository.”

The reliable way that works for everyone:

1. Install GitHub CLI from cli.github.com (download and run the installer like any app).

2. Open a terminal: on Mac, press ⌘-Space, type “Terminal”, press Enter. On Windows, press Start, type “PowerShell”, press Enter.

3. Paste this and press Enter, then follow the prompts (choose GitHub.com → HTTPS → Login with a web browser, and paste the one-time code it shows you into the browser page that opens):

   gh auth login

4. When it says “Logged in as <your-username>”, you’re set.

The app may also offer a direct “Connect GitHub” button

Some versions of the desktop app prompt you to connect GitHub in-app the first time you add a marketplace. If you see that, you can use it instead of the steps above. If you don’t, or it doesn’t work, gh auth login above is the dependable path.

Step 4: Add the toolkit’s marketplace

In the Claude Code prompt box, paste this and press Enter:

/plugin marketplace add unicorn-marketers/um-toolkit

This points Claude Code at the toolkit’s catalog.

If it says it can’t reach the repository

Two things cause this, check both: (1) Access not finished — make sure you accepted the GitHub email invitation from Step 1 (test by visiting github.com/unicorn-marketers/um-toolkit while logged in; if you see the page and not a 404, you’re in). (2) Your computer isn’t signed in to GitHub — run gh auth login from Step 3. Then run the command again. Still stuck? See Troubleshooting.

Step 5: Install the toolkit

Now install the plugin itself:

/plugin install um-toolkit@unicorn-marketers

That copies the whole toolkit (all 19 skills plus their rules, knowledge base, and templates) onto your computer. It usually takes under a minute: let it finish even if it looks paused.

Step 6: Load the new skills

Paste this and press Enter so Claude Code picks up what you just installed:

/reload-plugins

If the skills still don’t show up in the next step, fully quit and reopen the app. That always works.

Step 7: Confirm it worked

Type a forward slash in the prompt and start typing /um-toolkit. You should see the toolkit’s skills appear, each named like /um-toolkit:apollo, /um-toolkit:hermes, and so on.

Or just ask:

List the um-toolkit skills you can use.

If Claude lists them, you’re installed. 🎉

Step 8: Set up your brand

Installing the toolkit is half the job. The other half is teaching it about your brand, which is what makes everything it produces sound like you instead of generic AI.

The fastest way: type /um-toolkit:getting-started and press Enter (or just say “get me set up”). It walks you through everything one question at a time.

Keeping it updated

When the toolkit gets an update, pull it in with:

/plugin marketplace update unicorn-marketers

Your brand files are never touched by updates. More detail on the Updating page.
