# Releasing

## Prerequisites

1. Add `CARGO_REGISTRY_TOKEN` to GitHub repo secrets:
   - Get token from https://crates.io/settings/tokens
   - Add to repo: Settings → Secrets → Actions → New secret

## Release Process

```bash
# 1. Update version in Cargo.toml
vim Cargo.toml  # Change version = "0.1.0" to "0.2.0" etc.

git commit -m "Release v0.2.0"

# 3. Create and push tag
git tag v0.2.0
git push origin master
git push origin v0.2.0
```
