This ROM is for the International GT-I8730 ONLY! It is NOT for the SGH-I437! Just because Samsung named them both "Express" does not mean they have identical internal hardware!
CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.
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.

Just a notice: I don't have the device, I am a Galaxy Ace 3 LTE owner, but our devices are too similar and I decided to port CM12/12.1 to you
You can report bugs but you can't expect them to be fixed
