+=========================
+Software written in Prog8
+=========================
+
+Apart from the many `examples <https://github.com/irmen/prog8/tree/master/examples>`_ available in the source code repository,
+there are also larger pieces of software written using Prog8. Here's a list.
+
+
+`Assembler <https://github.com/irmen/cx16assem>`_
+    File-based assembler for the Commander X16.
+
+`Chess <https://github.com/irmen/cx16chess>`_
+    Chess game for the Commander X16, with 2-player or computer opponent game modes.
+
+`Image viewer <https://github.com/irmen/cx16imageviewer>`_
+    Multi-format image viewer for the Commander X16.
+    Can display C64 Koala, BMP, PCX and Amiga IFF images, including color cycling.
+
+`Petaxian <https://github.com/cyborgar/Petaxian>`_
+    Galaga type shoot em up game using only petscii graphics. Runs on C64 and Commander X16.
+
+`Rock Runner <https://github.com/irmen/cx16rockrunner>`_
+    Faithful Boulderdash clone, a well known arcade puzzle game from the 80's.
+    where you must collect all diamonds in a level while avoiding the hazards to reach the exit.
+    Can load the thousands of available fan made level files.
+    This game is for the Commander X16.
+
+`Shell <https://github.com/irmen/cx16shell>`_
+    Unix like command shell for the Commander X16.
+
+`Streaming Music Demo <https://github.com/irmen/cx16musicdemo>`_
+    Demoscene like "music demos" for the Commander X16.
+    They display graphics, animated song lyrics, and play a high quality sampled song streamed from disk.

 TODO
 ====
 
-- possibly optimize assembly output for (word1 & word2 ==0)
-    see attemptAssignToByteCompareZero() for assignment.
-    see testZeroOrJumpElsewhere() for if condition.
-
 - [on branch: shortcircuit] investigate McCarthy evaluation again? this may also reduce code size perhaps for things like if a>4 or a<2 ....
 - IR: reduce the number of branch instructions such as BEQ, BEQR, etc (gradually), replace with CMP(I) + status branch instruction
 - IR: reduce amount of CMP/CMPI after instructions that set the status bits correctly (LOADs? INC? etc), but only after setting the status bits is verified!
