Git Workflow

Learning Goals

Creating a New Repo

Oftentimes, we start a project by forking or cloning a pre-existing repository from GitHub. Today we are going to start from scratch and build our own! You’ll be working with a partner to run through the process of creating a new repo, adding some code, submitting pull requests, resolving merge conflicts and more!

Partner One

Pick one person to create the repo. The other person should be watching and advising!

Command Line

  • Use the command line to make a new directory called “git-collaboration-practice”
  • Add a file to your directory
  • Open up your directory in your text editor and add some text to that README

GitHub Time!!

  • Click the plus to create a New Repository
  • Run the steps of “…or create a new repository on the command line” starting with git init on the command line

Git Commands

  • Make a new directory mkdir name-of-directory
  • Change directories cd
  • Add a file touch

Cloning the Repo

Partner Two

Getting Started

  • Get the link to your partner’s repo
  • Clone it down to your machine

Working on the App

  • Create a new branch (what name makes the most sense here?)
  • Open up the repo in your text editor and add some text to that README
  • Add, commit and push that code to your branch


  • Create a pull request to merge your branch into main (DONT MERGE IT YET)
  • Add your partner as a reviewer

Git Commands

  • Clone a repo git clone linkToRepoHere
  • Create a new branch git checkout -b feature/name-of-feature-branch
  • Add a file to staging git add
  • Commit a file (with a message) git commit -m "description of work here"
  • Push changes git push

Code Review

Partner One


  • Check out your partner’s pull request on GitHub. Spend some time looking through the interface together. What information can you see about your partner’s code? How can you leave comments or request changes?
  • Why do you think its important to be able to review someone else’s code in this format?
  • Merge that pull request!

Continuing Work

Partner Two

  • Switch to your main branch
  • Pull down the changes that have been merged in
  • Why do you think its important to pull down changes before starting the workflow process again?

Merge Conflicts

Merge conflicts will happen to you at some point, and its important to learn how to resolve them successfully. A merge conflict happens when two branches change code in the same spot of a file and are attempted to be merged. Git doesn’t know which of the changes to keep, and needs our help to resolve the conflict.

Partner One

  • Make sure you are on your main branch
  • DONT pull down the changes that have been merged in (NOTE: This is BAD practice, we’re only doing it to trigger a merge conflict)
  • Make a change to the README
  • Add, commit and push those changes to main (NOTE: BAD PRACTICE - DONT DO IN REAL LIFE)
  • Resolve merge conflict in your text editor

Common Questions

Can I work on the same branch as my partner?
Yes! As long as a branch is pushed up to GitHub, anyone can pull it down and work on it. This is a common place for conflicts to arise though, so make sure you are communicating well and often. Sticking to different parts of the codebase is better practice to avoid merge conflicts for now.

When should I commit?

  • Early and often!
  • When you’ve completed one task or fix
  • You’re done for the day or reached a stopping point.
  • If you have code you want someone else to see

What is an atomic commit?

  • An “atomic” change revolves around one task or one fix.
  • Atomic means it could not be smaller

When should I submit a pull request?

  • When you’ve created a new, fully functional feature
  • When you have successfully solved a bug or fixed something broken
