WARNING: This guide is heavily outdated, and if you follow it, it's likely nobody will be able to help you if things go wrong.

Follow this guide and use GitKraken instead:

This guide uses TortoiseGIT. While there are other programs out there, this one is the most commonly used. This guide is for Windows only. TortoiseGIT is a simple enough program but other clients or the git command line are recommended once you are familiar with the basics.

It's recommended if you don't want to read this that you just watch this video:

Some further videos that are recommended watching for any git user: - Git from bits up - Linus Torvalds (yes that linus) on git

If you are having trouble[edit | edit source]

Watch this video guide if you are having difficulty with any step below. [1] If you have further problems, contact someone on #coderbus

Step 1 - Install Git[edit | edit source]

  • Go here:
  • Download the Windows Git program.
  • It should look something like 'Git-1.7.11-preview20120620.exe'
  • Install it and leave everything on default (just keep clicking next).
  • Wait till the installer has finished.
  • Step 1 over!

Step 2 - Register on Github[edit | edit source]

  • Head over here:
  • Click Signup and Pricing in the top right-hand corner.
  • Click the Create free account button'.
  • Create an account with your username and email.
  • Done!

Step 3 - Configure Git[edit | edit source]


  • Head here:
  • Follow the guide above from steps 2 to 4, you can install Git for Windows if you want however it's not recommended
  • Now you have Git all setup, but if you're command line illiterate like me, you'll wanna have some fancy graphics!

Step 4 - TortoiseGit[edit | edit source]

Step 5 - Forking Code[edit | edit source]

  • Head over to:
  • Click the Fork button in the top right corner.
  • The page you'll be directed to is now your fork. You'll be pushing updates here, and making pull requests to have them merged the main (master) repository.
  • Copy the HTTP URL. It's next to the HTTP GIT and Git Read-Only buttons. It'll look something like:

Step 6 - Downloading the Code[edit | edit source]

  • Find a computer folder where you don't mind the code sitting.
  • Right click and choose Git Clone...
  • The URL field should be filled with the URL of your Fork. If not, paste it in.
  • Click Next and watch flying tortoises bring you your code.

Step 7 - Setting up TortoiseGit[edit | edit source]

  • Right click on the folder that was created (usually called tgstation13), and go to TortoiseGit and then click on Settings.
  • Click on Remote under Git.
  • There should be one thing on the list of remotes, with the name: origin.
  • You're now adding the main repository as a source you can pull updates from.
  • In the Remote box type in upstream.
  • In the URL: box put:
  • Click Add New/Save.
  • Click Ok.
  • Almost done!

Step 8 - Updating your Repo[edit | edit source]

  • Updating your repo with the master should be done before trying anything.
  • Right-click the folder your repo is in and select TortoiseGit then Pull.
  • Click the radial button next to Remote and make sure upstream (or whatever you called it) is selected next to it.
  • The remote branch should be set to master.
  • Then click Ok. This will pull the latest changes from the master repo.

Step 9 - Making a Branch[edit | edit source]

  • Branching your repo is very important for organising your commits, you should have a different branch for each unrelated code change (e.g. if you wanted to make some new sprites for one item and change the properties of another these should be in seperate branches), as Pull requests work off branches rather than commits this will allow you to make a seperate Pull Request per change. Doing this streamlines the whole process and will save everyone a bunch of headaches.
  • Right-click in your working folder. Then choose TortoiseGit, and Create Branch...
  • Type in your new branch name
  • (Optional) Tick Switch to new branch
  • Press Okay and your new branch is created

To switch between Branches:

  • Right-click in your working folder. Then choose TortoiseGit, and Switch/Checkout...
  • Choose your Branch then press Okay

Step 10 - Making a Commit[edit | edit source]

  • A commit is confirmed change of the files in your repo, it's how you make changes permanently to the files in your repo, so try not to commit without making sure it works (though subsequent commits can fix it).
  • As said before, you should use different branches to separate your commits/changes. Don't commit to master. It should be clean, so you can fall back on it if needed.
  • To make your commits, you need to edit the files using BYOND's inbuilt editing tools. Make sure to follow coding standards when making your changes! When you're finished, right click the folder you're working with and choose Git Commit -> "[Your Branch Name]" (Example: Git Commit -> "My_First_Branch")
  • You can then select only the files you want to be committed by ticking or unticking them. You should also write a detailed commit summary, detailing what happened in that commit.
  • Click Ok and the commit will be committed to your local repo!

Step 11 - Making a Pull Request[edit | edit source]

  • Right-click in your working folder. Then choose TortoiseGit, and Push...
  • Set Local and Remote to the name of the branch you committed before. (e.g. My_First_Branch)
  • Under Destination, set Remote: to origin.
  • Click Ok. This'll upload your changes to your remote repo (the one on GitHub).
  • Head to your GitHub repo e.g
  • Click Pull Request at the top right.
  • Give this a quick read.
  • Fill out a summary and then create the pull request.
  • You're done! In many cases there will be issues pointed out by other contributors, unfortunate merge conflicts, and other things that will require you to revisit your pull request.
  • Optionally, view step 13 for a guide on cleaner commit logs, cleaner commits help maintainers review!

Step 12 - Checking Out Github PRs Locally (Optional)[edit | edit source]

  • This is a must for maintainers who need to easily test other people's code!
  • Locate the section for your Github remote in the .git/config file. Note that it is hidden by default. It looks like this:
[remote "upstream"]
fetch = +refs/heads/*:refs/remotes/upstream/*
url =
  • Now add the following line:
fetch = +refs/pull/*/head:refs/remotes/upstream/pr/*
  • Fetch from the upstream remote.
  • To check out a particular pull request, use Switch/Checkout and select the branch from the drop-down list.

Git command line verison[edit | edit source]

No editing of the git config file needed, just do git fetch <remote> pull/<pr>/head:target_branch usually something like git fetch upstream pull/26271/head:pr-26271.

Then you can checkout the target_branch

Step 13 - Clean commits (Optional)[edit | edit source]

  • This is a guide specifically for TortoiseGit, our recommended client
  • Your commit logs are filthy, full of one or two line commits that fix an error that makes you look bad, and the commit is called "Whoops" or "oops"
  • Navigate to your local version of the branch
  • Ensure it is up to date with the remote
  • Go to Show log
  • Select all the commits associated with this change or PR
  • Right click and choose Combine to one commit
  • This will open up the standard commit interface for TortoiseGit, with the commit logs of the selected commits merged together
  • Perform the normal routine for a commit
  • Go to push your branch to the remote branch
  • Ensure Force Overwrite Existing Branch (may discard changes) is selected to make sure the PR/Remote updates to contain just this squashed commit
