Generate a README from Your Codebase in One Shot
Staring at a blank README? Claude Code can read your project and write one for you in seconds.
Read the project structure and key files, then write a README.md that includes:
- Project overview and purpose
- Tech stack
- Setup and installation instructions
- Usage examples
Match the tone to the existing code comments.
Claude will explore the codebase, read your package.json or composer.json, check any existing docs, and piece together a coherent README. It's especially useful for internal tools and libraries that never got proper documentation.
# Generate docs for a specific module
claude "Read the /src/payments directory and write a PAYMENTS.md
explaining how the payment flow works for a new engineer joining
the team. Assume they know the language but not this codebase."
You can also point it at a specific audience:
Write a README.md aimed at non-technical stakeholders — focus on
what the project does, not how it works. Skip the setup instructions.
Claude adapts well to tone and audience — tell it who's reading and it'll calibrate. Once you have a first draft, ask it to fill in any gaps or expand specific sections.
Your README writes itself — you just need to ask.
Log in to leave a comment.
Set up Claude Code as an automated reviewer in your CI pipeline — on every pull request, it reads the diff, checks for bugs, security issues, missing tests, and convention violations, then posts its findings as a PR comment. Your human reviewers get a head start because the obvious issues are already flagged before they look.
Before deploying, tell Claude to read your project — migrations, environment variables, queue workers, scheduled tasks, caching, third-party integrations — and generate a deployment checklist that's specific to your app. Not a generic "did you run migrations?" list, but one that knows YOUR infrastructure and catches the things YOUR deploy can break.
Instead of writing a README from memory or copying a template, tell Claude to read your project and generate one that's actually accurate — real setup instructions from your config, real architecture from your directory structure, real API examples from your routes, and real prerequisites from your dependency files.
