 # Contributing to libmonochrome
 
-libmonochrome is a finished project by PierrotLL, and has been adapted to be used as a static library. It aims a full compatibility with addins using the 2011 version, so modifying is not a good idea, and adding things to the source code may be inappropriate as it is a finished project.
+libmonochrome is a finished project by PierrotLL, and has been adapted to be used as a static library. It aims a full compatibility with addins using the 2011 version, and is to be kept consistent, so keep that in mind if you want to add/modify things.
 
-However, if you want to contribute to everything around it (like building or packaging stuff), your help is welcome :)
+Perhaps the best way to start helping is to check the `TODO.md` file to see what needs to be done.

+# libmonochrome - TODO
+## Known bugs to correct
+- `ML_bmp`: one of the AND functions doesn't work well ;
+- `ML_get_contrast`: fix this.
+
+## To be done
+- Integrate a text module ;
+- Test other algorithms for full polygons ;
+- Add an `ML_horizontal_scroll_area` function ;
+- Add a function to draw lines with weight ;
+- Integrate a bitmap converter for beginners ;
+- Correct and enhance the documentation ;
+- Comment the code.
