+The main game for the Minetest game engine [minetest_game]
+==========================================================
+
+To build the wholeness of the Minetest project, insert this repository as
+  /games/minetest_game
+in the Minetest Engine.
+
+The Minetest Engine can be found in:
+  https://github.com/minetest/minetest/
+
+Compatibility
+--------------
+The minetest_game github master HEAD is generally compatible with the github
+master HEAD of minetest.
+
+Additionally, when the minetest engine is tagged to be a certain version (eg.
+0.4.dev-20120326), minetest_game is tagged with the version too.
+
+When stable releases are made, minetest_game is packaged and made available in
+  http://minetest.net/download.php
+and in case the repository has grown too much, it may be reset. In that sense,
+this is not a "real" git repository. (Package maintainers please note!)
