+# Django Admin
+
+!!!warning
+    Do not use the django admin unless you really know what you're doing.<br />You should never need to access it unless you are familiar with django or are instructed to do something here by one of the developers.
+
+The django admin is basically a web interface for the postgres database.
+
+As of Tactical RMM v0.4.19, the django admin is disabled by default.
+
+To enable it, edit `/rmm/api/tacticalrmm/tacticalrmm/local_settings.py` and change `ADMIN_ENABLED` from `False` to `True` then `sudo systemctl restart rmm`
+
+Login to the django admin using the same credentials as your normal web ui login.
+
+If you did not save the django admin url (which was printed out at the end of the install script), check the `local_settings.py` file referenced above for the `ADMIN_URL` variable. Then simply append the value of this variable to your api domain (`https://api.yourdomain.com/`) to get the full url.
+
+Example of a full django admin url:
