+# Chocolate Doom
+
+Chocolate Doom is neat for it's retro appeal, but it doesn't really work
+outside of a LAN party imo. I eventually went with Zandronum due to it's Linux
+support and modern online play capabilities.
+
+If you want to build this make sure you copy in extract_server.sh from above.

+You can use this to build a Odamex Doom server.

+I put a lot of work into this, but ultimately went with Zandronum due to it's
+compatibility with Linux. I couldn't get audio working with Odamex :(
