I found good project (boilerplate), which I am going to use as starting point for my project. And I forked it.
git clone https://github.com/fork.git forkdirectory # clone my fork to my local PC
git branch mybranch # create new branch for my specialities, which will be different from boilerplate
git checkout steklo # change the branch, which I will work on by default
Then I make some changes and check that they appear in my fork
git add . # add all changes for commit
git commit -m"commit comments" # make commit
git push -u origin mybranch # push changes to mybranch
I tested that for next changes I can just do shorter
git push
But what should I do when I will see that initial boilerplate updated?
1) How to apply all updates to my fork?
2) And then how to apply all updates from my fork to my local clone?
