Key points

• Git has two mechanisms for synchronization: pushing and pulling.
• git push takes your local commits and synchronizes the remote repository with those commits.
• git pull brings the commits from the remote repository and merges them with your local commits.

// push the remote main branch to local
git push origin master

• git pull is actually two commands in disguise: git fetch and git merge.

// pull the changes from the remote into your local
git pull origin

• git fetch pulls all of the commits down from the remote repository to your local one.
• git merge merges the commits from the remote into your local repository.

git checkout <our_branch_name>
git merge <their_branch_name>

• You can’t push to a remote that has any commits that you don’t have locally, and that Git can’t fast-forward merge.
• You can pull commits from multiple remotes into your local repository and merge them as you would commits from any other branch or remote.
• Check the remote that this git links to

git remote -v

• Add a git remote

git remote add <remote_name> <remote_url>
