+Releases and Changelog
+----------------------
+
+We use the `auto <https://intuit.github.io/auto/>`_ tool to generate the changelog and automatically release the project.
+
+`auto` is used in by GitHub actions, which monitors the labels on the pull request.
+This automation can add entries to the changelog, cut releases, and
+push new images to `dockerhub <https://hub.docker.com/r/centerforopenneuroscience/duct>`_.
+
+The following pull request labels are respected:
+
+    * major: Increment the major version when merged
+    * minor: Increment the minor version when merged
+    * patch: Increment the patch version when merged
+    * skip-release: Preserve the current version when merged
+    * release: Create a release when this pr is merged
+    * internal: Changes only affect the internal API
+    * documentation: Changes only affect the documentation
+    * tests: Add or improve existing tests
+    * dependencies: Update one or more dependencies version
+    * performance: Improve performance of an existing feature
