All our projects use Git, mostly with a repository hosted on GitHub. Since we're a small team, and most projects have less than three people working on it simultaneously, we have pretty loose Git guidelines since we rarely bump into conflicts.
Repo naming conventions
If the repo contains the source code of a site its name should be the main naked domain name of that site. It should be lowercased.
Sites that are hosted on a subdomain may use that subdomain in their name
If the repo concerns something else, for example a package, its name should be kebab-cased.
If you're going to remember one thing in this guide, remember this: Once a project has gone live, the master branch must always be stable. It should be safe to deploy the master branch to production at all times. All branches are assumed to be active; stale branches should get cleaned up accordingly.
Projects in initial development
Projects that aren't live yet have at least two branches:
develop. Avoid committing directly on the master branch, always commit through develop.
Feature branches are optional, if you'd like to create a feature branch, make sure it's branched from
Once a project goes live, the
develop branch gets deleted. All future commits to
master must be added through a feature branch. In most cases, it's preferred to squash your commits on merge.
There's no strict ruling on feature branch names, just make sure it's clear enough to know what they're for. Branches may only contain lowercase letters and hyphens.
Merging branches via GitHub pull requests isn't a requirement, but can be useful if:
- You want a peer to review your changes
- You want to ensure your branch can be merged and commits can be squashed via an interface
- Future you wants a quick way to retrieve that point in history by browsing passed pull requests
Merging and rebasing
Ideally, rebase your branch regularly to reduce the chance of merge conflicts.
- If you want to deploy a feature branch to master, use
git merge <branch> --squash
- If your push is denied, rebase your branch first using
There's not strict ruling on commits in projects in initial development, however, descriptive commit messages are recommended. After a project has gone live, descriptive commit messages are required. Always use present tense in commit messages.

Creating granular commits with
If you've made multiple changes but want to split them into more granular commits, use
git add -p. This will open an interactive session in which you can choose which chunks you want to stage for your commit.
Moving commits to a new branch
First, create your new branch, then revert the current branch, and finally checkout the new branch.
Don't do this to commits that have already been pushed without double checking with your collaborators!
git branch my-branch
git reset --hard HEAD~3
git checkout my-branch
Squashing commits already pushed
Only execute when you are sure that no-one else pushed changes during your commits.
First, copy the SHA from the commit previous to your commits that need to be squashed.
git reset --soft <commit>
git commit -m "your new message"
git push --force
Cleaning up local branches
After a while, you'll end up with a few stale branches in your local repository. Branches that don't exist upstream can be cleaned up with
git remote prune origin. If you want to ensure you're not about to delete something important, add a
