-This project uses semantic versioning. To create a new release:
+`npm version` automatically bumps the version in `package.json` and `package-lock.json`, creates a commit, and creates a git tag.
 
-1. Update the version in `package.json`
-2. Update the `CHANGELOG.md` with details of the changes
-3. Commit these changes with a message like "Bump version to x.y.z"
-4. Create and push a new tag:
-   ```
-   git tag -a vx.y.z -m "Release version x.y.z"
-   git push origin vx.y.z
-   ```

-When you push a new tag prefixed with "v" (e.g., v1.0.0), GitHub Actions will automatically:
-1. Build the package
-2. Run unit tests
-3. Create a GitHub Release with notes from your git history
-4. Publish the package to npm
