+# Changelog
+
+Since we follow [Conventional
+Commits](https://decisions.seedcase-project.org/why-conventional-commits),
+we're able to automatically create formal "releases" of the website
+based on our commit messages. Releases in the context of websites are
+simply snapshots in time of the website content. We use
+[Commitizen](https://decisions.seedcase-project.org/why-semantic-release-with-commitizen)
+to automatically create these releases using
+[SemVer](https://semverdoc.org) as the version numbering scheme.
+
+Because releases are created based on commit messages, a new release is
+created quite often---sometimes several times in a day. This also means
+that any individual release will not have many changes within it. Below
+is a list of the releases we've made so far, along with what was changed
+within each release.
