@ -134,6 +134,19 @@ add-on "The reckoning" for Quake 2, you should add: ``requires: quake-2``
You can also add complex requirements following the same syntax as the
``require-binaries`` directive described above.
Extensions / patches
--------------------
You can write installers that will not create a new game entry in Lutris.
Instead they will modify the configuration on an exsiting game.
You can use this feature with the ``extends`` directive. It works the same
way as the ``requires`` directive and will check for a base game to be available.
Example::
# Used in a installer that fixes issues with Mesa
extends: unreal-gold
Customizing the end of install text
