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. Linked below is a package that has come from another Android project that restore the Google parts. 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 if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review.

IMPORTANT INFORMATIONS

For complete installation instructions click here.

Root is now disabled by default on CyanogenMod 13. To enable it go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB.

CyanogenMod 13 comes with Cyanogen Recovery by default, if you don't like it you can flash alternative recoveries using IsoRec.

If you get an error message when flashing GApps you're probably running out of space in your /system partition. It is recommended to have 1GB to fit the ROM and the GApps ( The stock partition table has 512mb for /system). This thread has a good guide for repartitioning and this one has a great tool for repartitioning without Odin.

If you're interested in BLN, check this thread for a complete support of this feature.

Google is your friend

I'll not support users and answer questions from users which:
