Good point. Anik is a busy person, and as a community we can help out in other ways. I had a spare moment so I re-wrote the OP - [MENTION=6083514]Anik_khan[/MENTION], just hit reply (so you can see the contents of this post) and copy and paste what's in between the CODE tags over the OP:

LineageOS is a free, community built, aftermarket firmware distribution of Android 7.0 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

LineageOS 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. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS [URL="https://github.com/LineageOS"]Github repo[/URL]. And if you would like to contribute to LineageOS, please visit out [URL="http://review.lineageos.org/"]Gerrit Code Review[/URL]. You can also view the [URL="http://www.cmxlog.com/14.1"]Changelog[/URL] for a full list of changes & features.
