-After the release is published, we need to update the website.
-
-Check out the main branch of the [qunitjs/qunit](https://github.com/qunitjs/qunit) repository, and ensure it is clean and up-to-date. Run the following script, which will update release links and demos to use the new version:
-
-```
-qunit$ node build/site-set-version.js VERSION
-```
-
-Stage the changes it made, and commit with the following message:
-
-```
-Docs: Update url and version to VERSION
-```
-
-Push the commit to a branch on origin, wait CI checks to complete, then re-push to the main branch. Check the website in a few minutes to verify the change ([deployment log](https://github.com/qunitjs/qunit/deployments/activity_log?environment=github-pages)).
