# My Open Source Cheat Sheet

Fork your open source project you want to contribute into your GitHub and clone your fork.
``` 
git clone git@github.com:dcnis/mockito.git
```

Show current configured remote repositories. The `origin` repo points to your fork on GitHub. 
``` 
git remote -v
> origin  git@github.com:dcnis/mockito.git (fetch)
> origin  git@github.com:dcnis/mockito.git (push)
```
In order to fetch the updates from the open source project itself, you have to first add another remote usually called `upstream`.
``` 
git remote add upstream https://github.com/mockito/mockito.git
```
Now you have two remotes
``` 
git remote -v
> origin  git@github.com:dcnis/mockito.git (fetch)
> origin  git@github.com:dcnis/mockito.git (push)
> upstream        https://github.com/mockito/mockito.git (fetch)
> upstream        https://github.com/mockito/mockito.git (push)
```
Fetch new updates from `upstream` and merge them into your local `main` branch
``` 
git fetch upstream
git merge upstream/main main
```
