 8. Update the `CHANGELOG.md` to document changes to your extension.
 
+8. Push your repository to GitHub. A default set of GitHub Actions workflows is set up to
+test your code on Linux, Windows, Mac OS, and Linux using conda; upload code coverage
+stats to codecov.io; check for spelling errors; check for style errors; and check for broken
+links in the documentation. For the code coverage workflow to work, you will need to
+set up the repo on codecov.io and uncomment the "Upload coverage to Codecov" step
+in `.github/workflows/run_coverage.yml`.

 8. Make a release for the extension on GitHub with the version number specified. e.g. if version is 0.1.0, then this page should exist: https://github.com/rly/ndx-hed/releases/tag/0.1.0 . For instructions on how to make a release on GitHub see [here](https://help.github.com/en/github/administering-a-repository/creating-releases).
