# Rule Files

> Define project context and conventions for Tembo to follow.

Add a rule file to your repository root so Tembo understands your project's conventions, architecture, and coding standards. Tembo reads it before every session.

## Supported files

Tembo uses the first file it finds from this list:

* `tembo.md` (recommended)
* `AGENTS.md`
* `CLAUDE.md`
* `.cursorrules`
* `.windsurfrules`
* `.clinerules`
* `.rules`
* `AGENT.md`
* `.github/copilot-instructions.md`

## Example

```markdown theme={null}
