 ### Publishing a New Version
 
-To publish a new version of SLIM CLI to the Python Package Index, typically you'll update the `VERSION.txt` file; then do:
-```bash
-pip install build wheel twine
-python3 -m build .
-twine upload dist/*
+This project uses semantic versioning with automated release management. New versions are automatically published based on conventional commit messages.
+
+#### How It Works
+
+1. The project uses `python-semantic-release` to analyze commit messages and determine the appropriate version bump
+2. When changes are pushed to the `main` branch, a GitHub Actions workflow automatically:
+   - Determines the next version number based on commit messages
+   - Updates the version in `src/jpl/slim/VERSION.txt`
+   - Creates a GitHub release
+   - Builds and publishes the package to PyPI using trusted publishing
+
+#### Commit Message Format
+
+To properly trigger version updates, follow the [Conventional Commits](https://www.conventionalcommits.org/) format:
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+Where `type` is one of:
+
+- `feat`: A new feature (triggers a minor version bump)
+- `fix`: A bug fix (triggers a patch version bump)
+- `docs`: Documentation changes (no version bump)
+- `style`: Code style changes (no version bump)
+- `refactor`: Code refactoring (no version bump)
+- `perf`: Performance improvements (no version bump)
+- `test`: Adding or fixing tests (no version bump)
+- `build`: Changes to build system (no version bump)
+- `ci`: Changes to CI configuration (no version bump)
+- `chore`: Other changes (no version bump)
+
+Include `BREAKING CHANGE:` in the commit footer to trigger a major version bump.
+
+#### Examples
+
+Patch release (bumps 1.2.3 to 1.2.4):
+```
+fix: resolve issue with command line argument parsing
 ```
 
-(Note: this can and should eventually be automated with GitHub Actions.)
+Minor release (bumps 1.2.3 to 1.3.0):
+```
+feat: add support for custom configuration files
+```
+
+Major release (bumps 1.2.3 to 2.0.0):
+```
+feat: migrate to new API architecture
+
+```
