 ## Release Flow
 
-TODO
+### Changelog
+
+When delivering a new release, it is important to let your audience know what is the updated version offering.
+The best way of handling that is to attach the changelog.
+
+Changelog is a curated list containing information of any new features, fixes, deprecations, and so on.
+If provided, such list would be available in a couple of places: [CHANGELOG.md](./CHANGELOG.md) file,
+[Releases page][releases], [What's new][marketplace-plugin-page] section in Marketplace's Plugin page
+and inside of the Plugin Manager's item details. 
+
+There many different methods of handling the project's changelog. One of them, used in the current template project,
+is the [Keep a Changelog][keep-a-changelog] approach.
