Your first project with Claude Code

What you will make

You can launch Claude Code in the right folder, inspect one file change, and see the working contact link.

Before you start

A computer, a terminal, a project folder, and an account supported by Claude Code. Agent usage is billed by your provider.

1. Install and open

Use the official quickstart to install the CLI for your operating system. Open a new terminal and run claude --version. Change into your project folder, run claude, and complete sign-in. Keep credentials in the provider's sign-in flow.

2. Get your bearings

Ask the agent to explain the folder and identify the run and check commands before editing. Read existing project instructions. In a new folder, create one small HTML page first; you do not need a framework to learn the loop.

3. Make one change

Use the project brief to describe the audience, the result, and one acceptance check. Ask for a single change, such as adding a contact link. Let the agent edit the file and run the relevant check.

4. Review and keep

Open the result, inspect the diff, and ask what changed and what was checked. Keep the change once you understand it. If it is wrong, ask for a targeted correction; preserve unrelated work.

Give your agent a clear task

Read the project instructions and explain how this project runs. Then add one accessible contact link to the homepage, using the existing styling. Show the changed files and verify the link. Do not publish the site.
