 ## Authentication backends
 You can define which authentication backend to be used thanks to the `authentication-backend` option:
 * `internal` (default): _LMS_ uses an internal database to store users and their associated passwords (salted and hashed using [Bcrypt](https://en.wikipedia.org/wiki/Bcrypt)). Only the admin user can create, edit or remove other users.
-* `PAM`: the user/password authentication request is forwarded to PAM (see the default [PAM configuration file](conf/pam/lms) provided).
+* `PAM`: the user/password authentication request is forwarded to PAM. A default example PAM configuration file is provided at [`conf/pam/lms`](conf/pam/lms), which demonstrates how to authenticate using system passwords. **Note:** this file is just a base example; depending on your PAM setup, you may need to adjust the service file or PAM rules to ensure proper privileges.
 * `http-headers`: _LMS_ uses a configurable HTTP header field, typically set by a reverse proxy to handle [SSO](https://en.wikipedia.org/wiki/Single_sign-on), to extract the login name. You can customize the field to be used using the `http-headers-login-field` option.
 __Note__: the first created user is the admin user.

 The folder must follow a structure defined by Kodi, as detailed [here](https://kodi.wiki/view/Artist_information_folder). `artist.nfo` files are used to define additional artist information such as biography, sort name, and MusicBrainz ArtistID. See the format [here](https://kodi.wiki/view/NFO_files/Artists).
 
-__Note__: If no name is provided in the `artist.nfo` file, the name of the containing folder is used.
+The canonical artist name used by _LMS_ is the one specified in the `artist.nfo` file; If an `artist.nfo` exists but does not provide a name, the name of the containing folder is used.
+If no artist info file is provided, _LMS_ will pick the artist name found on the latest release.
 
 ### Filtering
 It is possible to apply global filters on your collection using `genre`, `mood`, `grouping`, `language`, `codec`, and by music library. More tags, including custom ones, can be added in the database administration settings.
