 ## Why Fragments?
 
 Using changelog fragments (similar to [Changesets](https://github.com/changesets/changesets) in JavaScript and [Scriv](https://scriv.readthedocs.io/) in Python):
 
 1. **No merge conflicts**: Multiple PRs can add fragments without conflicts
 2. **Per-PR documentation**: Each PR documents its own changes
-3. **Automated collection**: Fragments are automatically collected during release
-4. **Consistent format**: Template ensures consistent changelog entries
+3. **Automated version bumping**: Version bump type is specified per-change
+4. **Automated collection**: Fragments are automatically collected during release
+5. **Consistent format**: Template ensures consistent changelog entries
+
+## How It Works
+
+1. **During PR**: Add a fragment file with your changes and bump type
+2. **On merge to main**: The release workflow automatically:
+   - Reads all fragment files and determines the highest bump type
+   - Bumps the version in `Cargo.toml` accordingly
+   - Collects fragments into `CHANGELOG.md`
+   - Creates a git tag and GitHub release
+   - Removes processed fragment files
+
+## Multiple PRs and Bump Priority
+
+When multiple PRs are merged before a release, all pending fragments are processed together. The **highest** bump type wins:
+
+- If any fragment specifies `major`, the release is a major version bump
+- Otherwise, if any specifies `minor`, the release is a minor version bump
+- Otherwise, the release is a patch version bump
+
+This ensures that breaking changes are never missed, even when combined with smaller changes.
 
-## During Release
+## Default Behavior
 
-Fragments are automatically collected into `CHANGELOG.md` by running the collection script. This is handled automatically by the release workflow.
+If a fragment doesn't include a bump type in the frontmatter, it defaults to `patch`.
