 We use GitHub actions to publish new versions of this repository. To publish, perform the following actions:
 
 1. Ensure your local `main` branch is checked-out and current — `git checkout main && git pull origin main`.
-2. Run `npm version` to view the current version. Then…
-   * **For Normal Releases** use a keyword like `major`, `minor`, or `patch` (e.g., `npm version patch`).
-   * **For Release Candidates** manually declare the next version (e.g., `npm version 1.0.0-rc.57`).
+2. Run `npm run bump` to view the current version. Then, run the same command and provide the version to bump to (e.g., `npm run bump 1.0.0-rc.57`). Note, keywords like `major`, `minor`, `patch`, etc. are not supported — you must provide the full version string.
 3. Push the resulting commit and tags — `git push origin main --follow-tags`.
 4. In the GitHub UI, find [the tag you just pushed](https://github.com/Netflix/x-element/tags) and find the "Create release" option. Add any additional release information (including to check the box if it's a "pre-release", it probably is!).
