 * WP-Cron is setup to run via task/cron scheduler every 10 minutes. Set `PHP_CRON` environment variable to a valid [cron formated](https://en.wikipedia.org/wiki/Cron) schedule to change from the default execute interval. Be sure to apply the `define('DISABLE_WP_CRON', true);` setting in wp-config.php, so that WP-Cron does not slowdown your page loads. The last WP-Cron task run is logged to `/home/site/cron.log` 
   * Run `setup-wp-cron` from SSH shell to copy `cron.sh` to `/home/site` directory, if it does not exist already.
 
+## Container storage for site
+
+With the update to v1.2 of this container, the web server now serves the site from a local copy of the site that is synchronized from the durable storage. The container runs a synchronization service that will synchronize the `/home/site/` with `/var/www/vhosts/site-local/` bidirectionally. It monitors the `/home/site` directory for changes, if it detects changes it runs the synchronization. If it does not detect any changes, it will run a synchronization every two hours.
+
+### Commands
+
+These are supported commands that you can manually execute from the Azure App Service's SSH shell.
+
+* `sync-now` - Start a synchronization task immediately.
+* `clean-sync` - Initiates a fresh clean copy from durable to local
+  * Clears out local site's wwwroot directory 
+  * Clears folder's synchronization state
+  * Copies sync maintenance template to local site
+  * Copies site content from `/home/site/wwwroot` to `/var/www/vhosts/site-local/wwwroot`
+
+### Maintenance template
+
+When a fresh container is deployed or a container is regenerated from an updated docker image, the initial local site's wwwroot directory is empty. To minimize showing a *404* or *500* error while the site copies from durable to local storage, a `sync_maintenance.html` template file is copied to the root of the local site. If this file and the maintenance `.htaccess` exists, it will always be displayed to any browser accessing the site.
+
+#### Custom maintenance template
+
+You can place a `sync_maintenance.html` file with your own custom HTML within the `/home/site` directory in the durable storage. This would be the `/site` directory if uploading from FTP.
