+Creating stand-alone games
+  As ioquake3 is meant to be a reliable and stable code base, this engine is
+  ideal for your stand-alone game project. We made it easier for you to get a
+  binary that does not look for the original quake3 assets. The auth server
+  specific parts are disabled, too.
+  Just run make with the option BUILD_STANDALONE=1
+  Don't forget to edit the PRODUCT_NAME and subsequent #defines in
+  qcommon/q_shared.h and fill in your project info!
+  While a lot of work has been put into the ioquake3 that you can benefit from
+  free of charge, it does not mean that you have no obligations to fulfill.
+  Be aware that as soon as you start distributing your game with an engine
+  based on our sources we expect you to fully comply with the requirements
+  as stated in the GPL. That includes making sources and modifications you made
+  to the ioquake3 engine as well as the game-code used to compile the .qvm
+  files for the game logic freely available to everyone.
+  This does NOT mean that you cannot market this game commercially. All assets
+  (e.g. textures, sounds, maps) created by yourself are your property and can
+  be sold like every other game you find in stores.
