+## Judges' Comments
+
+We have seen entries with SDL graphics in the past, now it's time for SDL
+sound. This entry can even be run on a computer without a sound card with an
+appropriate setting of an environment variable - for that you'll have to dig
+into the SDL documentation.
+
+Can you figure out how the notes are encoded and program a different melody?
+
+### To build
+
+Download and install the portable [Simple DirectMedia Layer library](http://www.libsdl.org/)
+
+       cc -o jetro `sdl-config --cflags --libs` jetro.c
+
+### To run
+
+       ./jetro
+
+## Selected Author's Comments
+
+To compile the entry you need SDL library, which is used only for audio
+output. To run the entry make sure you have audio output available. The entry
+plays 22KHz 16 bit mono music with a small softsynth. When the music plays,
+you can stop the application by pressing enter, as the code will just wait
+with one call to getchar() before it quits.
