 - Disable and remove endpoints and functionality from Stirling-PDF. Currently the endpoints ENDPOINTS_TO_REMOVE and GROUPS_TO_REMOVE can include comma seperated lists of endpoints and groups to disable as example ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages would disable both image to pdf and remove pages, GROUPS_TO_REMOVE=LibreOffice Would disable all things that use LibreOffice.

+
+
+## Login authentication (CURRENTLY ALPHA TAG ONLY)
+### Prerequisites: 
+- User must have the folder ./configs volumed within docker so that it is retained during updates.
+- The environment variable 'login.enabled' must be set to true
+- The environment variables "INITIAL_USERNAME" and "INITIAL_PASSWORD" must also be populated (only required on first boot to create initial user, ignored after.)
+
+Once the above has been done, on restart a new stirling-pdf-DB.mv.db will show if everything worked.
+
+When you login to Stirling PDF you will be redirected to /login page to login with those credentials. After login everything should function as normal
+
+To access your account settings go to Account settings in the settings cog menu (top right in navbar) this Account settings menu is also where you find your API key.
+
+To add new users go to bottom of Account settings and hit 'Admin Settings', here you can add new users. The different roles mentioned within this are for rate limiting. This is a Work in progress which will be expanding on more in future
+
+For API usage you must provide a header with 'X-API-Key' and the associated API key for that user.

+### Q2: Why is my application downloading .htm files?
 This is a issue caused commonly by your NGINX congifuration. The default file upload size for NGINX is 1MB, you need to add the following in your Nginx sites-available file. client_max_body_size SIZE; Where "SIZE" is 50M for example for 50MB files.
