 If you have it installed in a dev environment and feel like you should clean it up completely (might be necessary after changes to the database), you can do so by:
 
-* Removing the `.env.local`
+* Removing the `.env` file
 * Load the {url}/main/install/index.php script again
 
 The database should be automatically destroyed, table by table. In some extreme cases (a previous version created a table that is not necessary anymore and creates issues), you might want to clean it completely by just dropping it, but this shouldn't be necessary most of the time.
