 Adding a new license
 ====================
 
-Adding a license is not straightforward in Moodle.
-
-1. You need to add the license to the database table "license" manually. For example:
-INSERT INTO license (shortname, fullname, source, enabled, version) VALUES ('short', 'fullname', '', 0, 2016112100);
-2. Add the english fullname to lang/en/license.php, e.g. append to the file:
-$string['short'] = 'fullname';
-3. Specify other translations via Site administration -> Language -> Language customisation
-4. Enable the new license on Site administration -> Plugins -> Licenses -> Manage licenses
-5. If you want to change the ordering of the licenses, you need to modify the row with the name "licenses" in the database table "config".
+Since Moodle version `3.9` you can add a custom license via Moodle's [license manager](https://docs.moodle.org/403/en/Licences#Licence_manager) in the Site administration.
