+==================
+Module Auto Update
+==================
+
+This module will automatically check for and apply module upgrades on a schedule.
+
+Upgrade checking is accomplished by comparing the SHA1 checksums of currently-installed modules to the checksums of corresponding modules in the addons directories.
+
+Installation
+============
+
+Prior to installing this module, you need to:
+
+#. Install checksumdir with `pip install checksumdir`
+#. Ensure all installed modules are up-to-date. When installed, this module will assume the versions found in the addons directories are currently installed.
+
+Configuration
+=============
+
+The default time for checking and applying upgrades is 3:00 AM (UTC). To change this schedule, modify the "Perform Module Upgrades" scheduled action.
+
+This module will ignore .pyc and .pyo file extensions by default. To modify this, create a module_auto_update.checksum_excluded_extensions system parameter with the desired extensions listed as comma-separated values.
+
+Usage
+=====
+
+Modules scheduled for upgrade can be viewed by clicking the "Updates" menu item in the Apps sidebar.
+
+To perform upgrades manually, click the "Apply Scheduled Upgrades" menu item in the Apps sidebar.
