 ## Notes
 
+* `grunt watch` when you're ready to start developing: this will watch for changes to Sass, Javascript, or images, and perform appropriate tasks (compiling Sass, minifying javascript, etc)
 * If this is a fresh install of Craft, you may see error pages until you've installed it by visiting  [http://craft.dev/admin/install](http://craft.dev/admin/install)
 * Crafty has a database-provisioning shell script. If you run `vagrant provision --provision-with shell`, the most recent backup in `app\craft\storage\backups` will be restored. (Of course, you'll lose any current state of the database, so only do this when you're happy for that to happen)
