I will assume you:
  • use Windows (64-bit)

  • have Visual Studio 2017 or 2019 installed on your computer

  • have an account on https://github.com

  • know how to code in C#

  • You need to take the following steps:
  • 1.Visit the openbullet repository here https://github.com/openbullet/openbullet

    After that, press the 

    Code:
    fork
  •  button on the top right corner. This will basically make a copy of the repository for yourself that you can modify at your own will.
  • 2.Install git from here https://github.com/git-for-windows/git/releases/download/v2.21.0.windows.1/Git-2.21.0-64-bit.exe and, when asked, select the full install and leave all the default options except for the text editor. As far as I can remember the default text editor that the installer suggests is 

    Code:
    vim
  •  but it might not be suitable for newcomers so you should select something graphical like Notepad++ or Sublime (you need to have them installed of course).
  • 3.Go to the folder 

    Code:
    C:/Users/YOUR_USERNAME/sources/repos
  •  (where 

    Code:
    YOUR_USERNAME
  •  is your actual user) and right click on an empty area, then select 

    Code:
    Open Git Bash here
  • . A terminal window will open.
  • 4.Type 

    Code:
    git clone https://github.com/YOUR_GITHUB_USERNAME/openbullet
  •  and press enter (replace 

    Code:
    YOUR_GITHUB_USERNAME
  •  with your actual username of course). This will start pulling all the files from your forked repository to your local computer so you can work with them.
  • 5.Open the 

    Code:
    OpenBullet.sln
  •  file with Visual Studio. Once you are inside, make a small change just to start you off (for example you could simply change the program name from 

    Code:
    OpenBullet
  •  to 

    Code:
    OpenBullet [My Mod]
  • ). Then save all the files you edited.
  • 6.Back to the git bash terminal, type:

    Code:
    git add --all
  •  which will add all the changed files to the commit we're going to make

    Code:
    git commit -m "Changed the program title"
  •  which will make a commit with the desired commit message

    Code:
    git push -u origin master
  •  which will push all the new commits to your repository.
    At the last command, git bash will most certainly ask for your github username and password, which you will need to provide in order to give it writing permissions to your repository.
  • At this point you can go search how to merge the changes I make on the master repository into your own fork, it's just a google search away and it will be a nice learning experience :] :ezy:
