CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo and Device Tree for Nypon is here Github repo.Feel Free to Contribute and Help in this Project .

GENERAL COMMENT AND REQUEST:

We ask all the regular contributors here to please answer the "xxx is broken" or "yyy force closes" statements without an attached logcat with something like "LOGCAT or it didn't happen"

Feel free to be creative but DO NOT respond with wipe cache/clear data or any other attempted solution before the reporting user has taken the trouble to actually try to help solve the problem (e.g. by attaching a logcat, detailed steps to reproduce etc.).

We need to force more discipline in how issues are reported which will help us all find and squash bugs that may exist.

Just clearing data etc. may in fact cause us to never find the bug that caused the issue and just makes for lazy users.
