Thanks to that we'll have a good release history. The users will be able to find specific versions of the action and will be able to track changes over time. It also improves the security as the build artifact will always get built in the CI environment, using a frozen lockfile.

When you're ready, you can merge the pull request and you can either publish the packages to npm manually or setup the action to do it for you.

+#### Custom Publishing
+
+If you want to hook into when publishing should occur but have your own publishing functionality, you can utilize the `hasChangesets` output.
+
+Note that you might need to account for things already being published in your script because a commit without any new changesets can always land on your base branch after a successful publish. In such a case you need to figure out on your own how to skip over the actual publishing logic or handle errors gracefully as most package registries won't allow you to publish over already published version.
