Creat a new branch and do the merge

• In your Github fork, you need to keep your master branch clean, by clean I mean without any changes, like that you can create at any time a branch from your master. Each time that you want to commit a bug or a feature, you need to create a branch for it, which will be a copy of your master branch. When you do a pull request on a branch, you can continue to work on another branch and make another pull request on this other branch.

• Before creating a new branch, pull the changes from upstream. Your master needs to be up to date.

$ git pull

• Create the branch on your local machine and switch in this branch :

$ git checkout -b [name_of_your_new_branch]

• Push the branch on github :

$ git push origin [name_of_your_new_branch]

• When you want to commit something in your branch, be sure to be in your branch. Add -u parameter to set-upstream.

• You can see all the branches created by using :

$ git branch -a

• Which will show :

• approval_messages master master_clean

• Add a new remote for your branch :

$ git remote add [name_of_your_remote] [name_of_your_new_branch]

• Push changes from your commit into your branch :

$ git push [name_of_your_new_remote] [url]

• Update your branch when the original branch from official repository has been updated :

$ git fetch [name_of_your_remote]

• Then you need to apply to merge changes if your branch is derivated from develop you need to do :

$ git merge [name_of_your_remote]/develop

• Delete a branch on your local filesystem :

$ git branch -d [name_of_your_new_branch]

• To force the deletion of local branch on your filesystem :

$ git branch -D [name_of_your_new_branch]

• Delete the branch on github :

$ git push origin :[name_of_your_new_branch]

• The only difference is the: to say delete, you can do it too by using GitHub interface to remove branch: https://help.github.com/articles/deleting-unused-branches.

• If you want to change default branch, it's so easy with GitHub, in your fork go into Admin and in the drop-down list default branch choose what you want.

• If you want create a new branch:

$ git branch <name_of_your_new_branch>
