+- name: GFX Tutorial, Part I
+
+### Description
+
+The first in a long sequence of _prototyping releases_. Every release will
+change a tiny bit of the application, starting with nothing related to the game
+at all, slowly building towards something that takes on a familiar shape,
+representing what is described in the design documentation.
+
+In the first couple of releases, the GFX tutorial is completed step by step, to
+get a feel for the low-level graphics programming requirements.
