Git for Humans: How to Get Started with Git in Your Agency Today

Linus Torvalds is a genius, and Git is an amazing feat of software engineering, but there's a big problem: the learning curve. Git is pretty tough to wrap your head around. You see, Git wasn't made for humans; it was made for Linux kernel developers.

How do you start with Git in your agency? How can web designers (mostly human, as far as I can tell) start using a tool built for GCC-toting neckbeards? What if I told you it's not only possible, it's actually downright easy?

The first step

The first step in getting started with Git in your agency is to get buy-in. The moment you wrap your head around the basic use cases for Git, you get a little high on power. I know, I was there. The first time I created a local branch without a network connection and later rebased it on someone else's changes without cluttering the history, I became so overconfident that I thought I could fly. I jumped off a building, just like when kids discover drugs in those after school specials.

It's a mistake to roll with that confidence and then just plop Git in front of your coworkers. It won't work. You've had the epiphany, but they haven't, and they may never. And let's be honest: If you didn't have that glowing insight into what Git can do for you, would you be motivated enough to work through the vicious learning curve? You have the religion, my friend, and so you are willing to put up with pain and agony because you know the reward is worth it.

Your coworkers don't have the religion, and proselytizing is not the answer. You can't just stand on a milk crate in the middle of the office,tell everyone about the Kingdom of Git, and expect to get buy-in. People won't believe in miracles unless they see them with their own two eyes. But we both know that Git doesn't exactly offer a rewarding first-use walkthrough — there are no miracles there.

The point is, you will be tempted to use your new knowledge of distributed source control to craft the perfect solution for your agency. It's easy to go overboard. You'll have three different branches representing production, quality assurance and development. Every feature will get its own branch. All merges will use interactive rebases to keep the history clean. You create documents with lots of circles and lines explaining how the code will "flow" from repo to repo. It will be perfect, so you think.

If you do this, you will fail, because you will have taken what is already an intense learning curve and turned the dial up to 11.


The only way to introduce Git to a novice is to start with the basics. The very basics. And the only way to get your coworkers to start using Git consistently is if they get value out of it immediately. Don't forget; this is Git and there will be blood, but you can keep it to a minimum.

Your Git starter kit

Note: This is just to get started. For example, I say, "Don't use local branches," but I'm not saying local branches are bad. I LOVE local branches. Just don't go there when you are rolling Git out for the first time to people who have never used source control.

Create a repo for every client and/or project, no long-lived branches, and copy-paste shared code.

Git has performance problems with large code bases. Maybe each of your projects is small, but it won't take many projects to start gunking up the works. Once you start adding large binary files like images, videos, etc. (and you will, it's just easier to put everything in one place and you have work to get done), Git will quickly hit a performance wall. Nothing kills adoption of a new tool quite as quickly as performance problems. So create a fresh, empty repo for each new project.

If you start a new repository for every new client or project, how do you share common code? Just copy-paste it from each project. Yeah, this somewhat defeats the purpose of version control. If you're a purist you probably stopped reading this a while ago, so I suspect you are someone trying to get work done on something other than an operating system kernel. Git does have mechanisms for sharing common code across repos, but you're trying to keep the learning curve to a minimum and everyone already knows how to copy-paste. It will be fine, I promise. And if you reach the point where it becomes a problem, everyone will have enough Git skills at that point to do it the right way.

Share code often, don't use rebase, and don't use local branches.

Long-lived branches are the beginning of the end. You don't know pain until you've tried to merge two months of local, unshared changes with the main repository on a project.

The key to pain-free Git is to get your changes to everyone else on your team as often and as fast as possible. Merge conflicts are totally manageable in small doses. They're like sprint intervals. One is fun, but eight in a row? You'll be "tossin' your cookies," as coach used to say. Plus, have you ever tried to teach someone about remote repositories in Git? Yeah, best avoid it until later.

How do you avoid the problem? Don't use branches. Yes, local branches are one of the most amazing features in Git. But you should start everyone off as if they don't exist — add them later when everyone is more comfortable.

Instead, pretend like Git is an old school centralized version control system. Every few commits or any time you hit a somewhat stable point, pull changes from the master repo, merge the changes, and push your changes to the central repository.

Rebase keeps the history clean, but it creates merge conflicts more often and is harder to understand. So don't use it. A clean history is a nice to have, but avoiding painful merge conflicts is mission critical for Git adoption in your company. And that's why you shouldn't use local branches (at first). Local branches encourage people to hide their work and wait until it's perfect before sharing with everyone. This pattern is how you create integration risk, a recipe for certain disaster.

Use the command line client.

This will be the most controversial recommendation.

"The command line," you say, "I thought we were trying to lower the learning curve? How does an archaic, text-based user interface help with that?!?"

Because it turns out that most people are very good at following rote instructions to achieve a result. Most of us spent over a decade in school learning how to do plug 'n chug algebra and sentence diagrams — you can handle a short, easy to memorize series of incantations typed into a little black box. It's nothing compared to the quadratic formula.

The trick here is not to teach someone how to use the command line, but instead put together a little cheat sheet for the basic commands they need. You're going to need to CD to the correct place and clone the repository to get started, so you need a cheat sheet for "How to clone your first repo." Then you need to make some changes and save them to Git. Then you need to merge, handle a merge conflict and push changes.

All of that can fit on one or two cheat sheets sitting in a shared folder somewhere. People will run into problems the cheat sheets can't handle, but if you keep everything as simple as possible, it won't happen often. You do need at least one Git "expert" in the office to help solve those strange problems beginners will inevitably run into.

Handle merge conflicts manually.

A merge conflict is befuddling the first time you encounter one. This is why you should NOT add a conflict resolution tool to an already confusing situation. Merge tools and visual diff tools are great once you wrap your head around them, but if you are following the guidelines above (no long-lived branches, merging often), merge conflicts will be rare and small. A visual diff tool is unnecessary.

It's pretty easy to fabricate a merge conflict to show someone how to handle the situation. So to demonstrate a merge conflict resolution, create a merge conflict and open up the "conflicted" file with a text editor. You will see little marks like this:


if name == "main":\n\n    text = Text()\n<<<<<<< HEAD\n    text.packit!!!!\n=======\n    text.packit???\n>>>>>>> master\n    text.delete(1.0, END)\n

Check it out. The bottom arrows point to "master", so that's on the master branch. The top arrows point to HEAD, and then there are equal signs between the two alternatives. The top one, the HEAD one? That's your change. Which one do you want? Edit the file to look the way you want it to, save the changes, and commit them. Then try the pull/push process again.

Visual diff tools wrap a simple exercise of editing a file into a complicated application that is awesome for experts but unnecessarily confusing for beginners.


Before you roll out Git to everyone on your team, you should do a little bit of training. I recommend a simple demonstration. Give a high (really, really high and not complicated) level walk-through of Git and the development model you are recommending. Recommend a very simple development model as outlined above.

Be sure to explain the benefits of using Git. Tell everyone how easy this will make it for them to share code and assets, and how it will keep them from losing work. Git is like a giant undo button for your entire project.

Then go through each of the cheat sheets and walk through a merge conflict. After you are done, pass out your cheat sheets and send out instructions for installing Git.

Explain the concept of the working directory, index, and commits. Make sure they use git status all the time to see what state their files are in. Show, don't tell. This is one of Git's complexities that needs to be understood thoroughly because it will avoid an entire class of problems most people have, and it will help avoid data loss. On your cheat sheets, make sure everyone does 'git add .' before a commit, and of course most of the common gotchas will disappear.


It actually took me years to develop this process. I tried to bring distributed version control into my last organization many times, and I failed many times. The main point of failure was Git's complexity. There is great power with that complexity, but the learning curve is almost unapproachable for mere mortals without a ton of help and motivation.

If you don't have the Git religion yet and are looking for a simple guide to getting up and running with the basics, there's an entire chapter devoted to the topic in my book, Sketching with CSS.

Hey there, I'm Sean.

I'm probably a lot like you. I make stuff for the web. I have a CS degree, but the last 11 years of my career have been a more potent teacher.

Sean Fioritto

Recently, I wrote a book on web development called Sketching with CSS. I also run a training company for developers. I'm an author in Smashing Magazine and I've written some cool open source projects.

Today, I'm an entrepreneur. In the not so distant past I did the usual 9-5 thing doing web development for a couple of big companies.

I'd love to meet you on Twitter.
