# Contributing to cqs


Thank you for your interest in contributing to cqs!

## Development Setup


**Requires Rust 1.88+** (check with `rustc --version`)

1. Clone the repository:
   ```bash
   git clone https://github.com/jamie8johnson/cqs

   cd cqs

   ```

2. Build:
   ```bash
   cargo build

   ```

3. Run tests:
   ```bash
   cargo test

   ```

4. Initialize and index (for manual testing):
   ```bash
   cargo run -- init

   cargo run -- index

   cargo run -- "your search query"

   ```

5. Set up pre-commit hook (recommended):
   ```bash
   git config core.hooksPath .githooks

   ```
   This runs `cargo fmt --check` before each commit.

## Code Style


- Run `cargo fmt` before committing
- No clippy warnings: `cargo clippy -- -D warnings`
- Add tests for new features
- Follow existing code patterns

## Pull Request Process


1. Fork the repository and create a feature branch
2. Make your changes
3. Ensure all checks pass:
   ```bash
   cargo test

   cargo clippy -- -D warnings

   cargo fmt --check

   ```
4. Update documentation if needed (README, CLAUDE.md)
5. Submit PR against `main`

## What to Contribute


### Good First Issues


- Look for issues labeled `good-first-issue`

- Non-CUDA GPU support (ROCm for AMD, Metal for Apple Silicon)
- VS Code extension
- Performance improvements
- CLI enhancements

### Bug Reports
