Merge two git repositories

# clone 1st project
$ git clone git@REPOSITORY_URL:project1.git
$ cd project1

# add 2nd project into remote source
$ git remote add -f proj_2 git@REPOSITORY_URL:project2.git

# checkout the branch you want to keep, for example: origin/master
$ git checkout BRANCH_1
HEAD is now at 10eb427...

# then merge the other branch, for example: project2/master
$ git merge --allow-unrelated-histories BRANCH_2

# after resolving conflicts, commit and push back to remote branch, for example: origin/master
$ git push origin HEAD:master --force
