Here is a basic reference for collaborative git commands:
Checkout a remote branch
# list branches first git branch -a # * master # remotes/origin/branch_name git checkout -b local_name remotes/origin/branch_name
Merging
# switch to master git checkout master # merge with experimental branch git merge experimental
Create a tag
# list tags git tag # add a tag git tag tagname # push to remote git push origin master --tags
