 ## Notes and Issues
 
-### Compilation problems
 
-Note the tool chain used in overview section, If you have trouble compiling on other 
-platforms or OS. For example 64-bit OS, user may need to remove or edit
-some of the CCFLAGS in root directory Makefile to allow for Compilation, if you see them throwing errors
-See [pull request on SSD1306 project](https://github.com/gavinlyonsrepo/SSD1306_OLED_RPI/pull/2) for details.
-Will upgrade in future release.
