 ### Authentication
 
+#### Providers
+
 Share Me loads the configured PocketBase authentication providers. Head to your PocketBase admin dashboard, go to Settings > Auth providers and configure the ones you want to use.
 
+#### Disabling Username/Password
+
 To disable username/password and email/password login if you only want to allow access via SSO, go to Collections > users > Settings (cog icon) > Options and disable/enable the methods you want.
 
+If you only want to disable sign-up, remove the "create" API rules to only allow admins to create new users. You can set the `SIGNUP_ENABLED` environment variable in the frontend to disable the sign-up page and remove links to it.
