You just paid $20/month for Claude Pro.

Here's how to actually use it (3 steps, 15 mins):

_

1. Open Claude on your browser.

2. Select "Opus 4.7" with Extended Thinking on.

3. Paste this prompt:

Interview me with AskUserQuestion to build my about-me .md file. Cover: my role, my audience, what good output looks like, and what I hate. Keep the final file under 2,000 words.

4. Answer the questions.

5. Save the output as about-me .md on the desktop.

6. Copy-paste my detailed interview prompt to build 'about-me' file from here: ruben.substack.com/p/yo…

_

Now most people stop here.

But here's where Claude gets powerful:

✦ Set up your Cowork folder.

1. Download the Claude desktop app.

2. Create a folder called "Claude" on your computer.

3. Drop your about-me .md inside.

4. Open the desktop app. Click the Cowork tab.

5. Select your folder.

6. Go to Settings → Cowork → Global Instructions.

7. Paste:

Read about-me .md before every task. Save outputs to this folder.

5 more minutes. Done.

_

✦ Run your first real task.

1. Pick a task you do every day. An email. A brief.

2. Then paste this 20-word prompt:

I want to [task] for [audience]. Read my folder. Use AskUserQuestion before you start.

3. Claude generates a form. Click the answers.

4. The output sounds like you, not like AI.

5. If it doesn't, add what's missing to about-me .md and run again.
