Setting Up Git

  1. Create a GitHub account

  2. Install Git

    1. Note Git is already installed on macOS

    2. Download for Windows

      1. (non-WSL) Make sure you install Git Bash along with your installation, and leave everything else default

      2. (WSL) from WSL: sudo apt install git

    3. If you’re already using Linux I bet you know what Git is

      1. For Ubuntu, run apt-get install git

      2. For Arch Linux, run pacman -S git

  3. Set up SSH tokens (do this from WSL if using WSL)

    1. First, run ssh-keygen in a terminal anywhere, and just leave everything default by pressing enter

    2. Navigate to ~/.ssh/ and open id_ed25519.pub or id_rsa.pub in a text editor

      1. This is a hidden directory, so on Windows you might need to enable hidden folders if in GUI. Note on WSL this is File Explorer → Linux → Ubuntu → home → your name → .ssh → id_rsa.pub

      2. To open from terminal if you have VSCode installed, run code ~/.ssh/id_ed25519.pub

    3. Copy the ssh key listed in this file into your GitHub’s SSH keys here

    4. If you have multiple machines, you’ll need to do this for each machine (i.e. dual booting or using a VM)

  4. Run these two commands to save your GitHub credentials, but put in your own credentials (from WSL if using WSL)

    1. $ git config --global user.name "John Doe" $ git config --global user.email johndoe@example.com
  5. View the Git 101 Presentation below if you’re not familiar with Git

Getting Up to Speed with the NER GitHub

Here is the NER GitHub, it might be a good idea to bookmark this if you’ll be doing a lot of stuff in it

You might need to get added to it, so either fill out the form at the top of the page or talk to your lead/head about getting access

Assuming you have GitHub access, Git installed on your machine, and SSH keys set up, you should be entirely ready to clone a repo! If you are confused by any of the terminologies I go into below, use the “Git 101” presentation above for reference.

Upon loading the page, you’ll be presented with a bunch of repos that NER uses. Here are some of the big ones for engineering:

  • Cerberus

  • shepherd_bms and ShepherdBMS-2

  • Ner_Processing

  • Odyssey

  • Finishline

  • LVEmbedded22

  • Schematics22A

Now let’s say you actually want to contribute, so you’ll want to clone whatever repository you're going to be working in. I want to clone the Cerberus repo, I'd go into that repo, click on the green "Code" button above the file structure in the repository and copy the link, so it would be

git clone git@github.com:Northeastern-Electric-Racing/Cerberus.git

Remember:

  • To update the submodules within the repo on initial clone, run: git submodule update --init --recursive

  • To pull the latest changes from the dependencies, run git submodule update --remote
