Install VS Code

VS Code is the free code editor you'll build in today. Download it, install it like any other app, and open it.

Download VS Code

Optional, if your table lead suggests them:

• Git saves versions of your work so you can go back.
• Node.js (LTS) runs most of the web apps Cline builds.

Add Cline to VS Code

Cline is the AI assistant that writes and runs code for you inside VS Code.

1. In VS Code, open Extensions from the bar on the left, or press Ctrl+Shift+X (Cmd+Shift+X on a Mac).
2. Search for Cline and choose Install.
3. A Cline icon appears in the bar on the left. Click it to open Cline.

Can't find it? Open Cline in the VS Code Marketplace.

Connect Cline to Claude

1. If Cline asks you to sign in, choose to use your own API key instead.
2. For API Provider, choose Amazon Bedrock.
3. For authentication, choose API Key and paste the API key from your build pass.
4. For AWS Region, choose the region on your build pass.
5. Turn on Use cross-region inference.
6. For Model, choose Claude Sonnet 4.6, then save.
7. Type Hello in the Cline chat. If Claude answers, you're connected.

If Cline says there are too many requests, wait a few seconds and try again. Everyone in the room shares the same connection to Claude.

Write your idea

Fill in each section in plain words. Cline reads this file to understand what to build, so the clearer it is, the better the first version will be.

Download idea.md Copy

Use it in Cline

1. Make a new folder for your project, for example Documents/my-idea.
2. In VS Code, choose File, then Open Folder, and pick that folder.
3. Save idea.md into the folder.
4. In Cline, stay in Plan mode and type: Read idea.md and make a plan for this project.
5. When the plan looks right, switch to Act and type: Build the first task.

Start building

• Cline asks before it changes files or runs commands. Read what it wants to do, then choose Approve.
• Ask for one change at a time, then check it before asking for the next.
• When something looks wrong, describe what you see, for example The Save button does nothing when I click it.
• Ask Cline to run the app and tell you the address to open in your browser.
• Keep private data out: no real passwords, customer records, or anything confidential.
• At 1:15, ask Cline: Help me plan a two-minute demo of what works.
