# CodeTrain documentation

Everything published about how CodeTrain works, in one place. Pick the section that matches what you are doing.

## Using the product

- [The homepage](https://codetrain.ai/) runs a real lesson in the browser with no account. It is the fastest way to see what a step looks like and what happens when your code does not pass.
- [The course catalog](https://codetrain.ai/learn/) lists every curated course and class. These are the starting point rather than the product: the tutor writes a lesson on any topic you name, or on any public repository you paste.
- [How the Socratic method works here](https://codetrain.ai/learn/socratic-method/) is the exact contract the tutor keeps, quoted from the code that enforces it.
- [Learning an unfamiliar codebase](https://codetrain.ai/learn/understand-a-codebase/) covers repo mode and what it refuses to read.

## Building against CodeTrain

- [Developer API](https://codetrain.ai/developers/): the public REST endpoints, rate-limit headers, the versioning policy, and how to install the command line tool.
- [/llms.txt](https://codetrain.ai/llms.txt): when to reach for CodeTrain, and every page as markdown. Read this first if you are an agent.
- Any page on this site serves markdown to a client that asks for it with `Accept: text/markdown`.

## Trust and data

- [Security and data handling](https://codetrain.ai/security): where your code goes, what is stored, and how to report a vulnerability.
- [Privacy policy](https://codetrain.ai/privacy): what we collect and how to have it deleted.
- [Terms of service](https://codetrain.ai/terms).
- [About CodeTrain](https://codetrain.ai/about/) and [how to reach a person](https://codetrain.ai/contact/).

## What is changing

- [Changelog](https://codetrain.ai/changelog/): what shipped and when, newest first.
- [Roadmap](https://codetrain.ai/roadmap/): what is being built, what is next, and what we are still thinking about. Shipped items link to the changelog entry that proves it.
- [Comparisons](https://codetrain.ai/compare/): how CodeTrain differs from coding assistants, AI course builders, chatbot study modes and traditional course platforms.
- [Conductor Network](https://codetrain.ai/conductors/): the referral programme and how payouts work.
