+
+This folder contains helper files for releasing the images and manifests of the
+web app.
+
+## Steps for releasing

+    RELEASE_BRANCH="release-0.7"

+    ```
+2. Update the VERSION file with the corresponding tag
+3. Update the app's kustomization file to use the new tag
+4. Submit the PR
+5. Once merged the GH Action will tag and push an image based on the contents
+   of the VERSION file
