@mh.kaya @Andy_at_Focallocal Hi and welcome. the steps to do a pull request are the folowing:
You first create a fork of fl-maps.
Then you clone you're fork on youre computer.
You set up 2 remotes: you're fork named origin, and the fl-maps named upstream
Before begining working on the code, you always pull everithing from upstream inside you're master, then you crete a new branch, example - fixingBug
When you are ready to upload the code, you create a push on you're ORIGIN remote.
Lastly, you go on github, inside you're fork page, and you will see a button -- CREATE PULL REQUEST
The most important thing before starting is to ALWAYS pull everithing from the UPSTREAM remote, ALWAYS
If you have any more questions i am here.
