+title: Automatic Update Detection
+
+## Introduction
+
+When you push a change to your Git repository, ContentDB can create a new release automatically or
+send you a reminder. ContentDB will check your Git repository every day, but you can use
+webhooks or the API for faster updates.
+
+## Setting up
+
+* Set "VCS Repository URL" in your package.
+* Go to the Create Release page and click "Set up" on the banner.
+* If the "How do you want to create releases?" wizard appears, choose "Automatic".
+* Choose a trigger:
+    * New Commit - this will trigger for each pushed commit on the default branch, or the branch you specify.
+    * New Tag - this will trigger when a New Tag is created.
+* Choose action to occur when the trigger happens:
+    * Create Release - A new release is created.
+    * Notification - All maintainers receive a notification under the Bot category, and the package
+      will appear under "Outdated Packages" in [your to do list](/user/todo/).
+
+## Configuring
+
+See the [Package Configuration and Releases Guide](/help/package_config/) for
+documentation on configuring the release creation.
+You can set the min/max Minetest version from the Git repository, and also
+configure what files are included.
