+# raylib roadmap
+
+Here it is a wish-list with features and ideas to improve the library. Note that features listed here are usually long term improvements or just describe a route to follow for the library. There are also some additional places to look for raylib improvements of ideas:
+
+ - [GitHub Issues](https://github.com/raysan5/raylib/issues) has several open issues for possible improvements or bugs to fix.
+ - [raylib source code](https://github.com/raysan5/raylib/tree/master/src) has multiple *TODO* comments around code with pending things to review or improve. 
+ - [raylib wishlist](https://github.com/raysan5/raylib/discussions/1502) is open to everyone to ask for improvements, feel free to check and comment.
+
+_Current version of raylib is complete and functional but, as always, there is lot of room for improvement._
