A guide for using git.
The first line of commit message should be the format of ISSUE <issuee number> - <issue message>. Every commit should have a corresponding issue.
Note: Pull request will not be used. After squashing commits into one using 'git rebase', please checkout to master by git checkout master and cherry-pick that commit with git cherry-pick <branch-name>. Make the push after that.
