Install Claude

Claude is the AI that builds your SaaS with you. You do not need to know how to code: you talk to it normally, in plain English. You need a Mac or Windows computer (not a phone), a bank card and internet.

1. Create your account and get the Pro plan

Go to claude.ai and create an account with your email. Go to claude.com/pricing and pick the Pro plan, around $20 a month. The free plan is not enough: it does not include Claude Code, the tool that builds your site. You pay Claude directly, it is not included in the pack.

2. Install the Claude app

Go to claude.ai/download and download the Mac or Windows version. On Mac, open the downloaded file, drag Claude into Applications, then open it. On Windows, double-click the file, follow the installer, then open Claude from the Start menu. Sign in with your account. No terminal needed.

3. Put your folder somewhere safe

Find the .zip file you downloaded from Tenseat, usually in Downloads. On Mac, double-click it. On Windows, right-click, then "Extract All". Move the resulting folder into Documents, without renaming it or removing anything from it.

4. Open this folder in Claude

In Claude, click the Code tab at the top left. Below the box where you type, click the first button and choose the first line under Local. Click the button right next to it, then Open folder…, and pick your folder in Documents. If you cannot see a button, tell Claude: "I cannot see Open folder, what should I do?".

5. Pick the model and the mode

Below the box where you type, pick the Sonnet model. If you are unsure, leave the one already selected. Right next to it, pick the Auto mode if you see it, otherwise Accept edits: Claude moves forward on its own instead of asking permission for every file. Your plan has a usage limit. If Claude says you reached it, wait until the time it shows, then type "continue". If it blocks you often, you can move up to the next plan.

6. Paste one message

Open PROMPT.md, copy everything, paste it into Claude and press Enter.

7. Follow along

Claude first asks you a few questions, one at a time. Answer in your own words. Then it works in one go: your brand, your product, your sales page, your accounts, going live. It will sometimes ask permission: that is normal, click Allow. Plan on several sessions.

If you get stuck

Tell Claude what you see, in your own words. If you do not understand it, tell it "explain that more simply". If the chat cuts off, open a new one in the same folder and paste the message again: it picks up where you left off.
