Clone the fork on your local machine. Your remote repo on Github is called origin.
Add the original repository as a remote called upstream.
If you created your fork a while ago be sure to pull upstream changes into your local repository.
Create a new branch to work on! Branch from develop if it exists, else from master.
Implement/fix your feature, comment your code.
Follow the code style of the project, including indentation.
If the project has tests run them!
Write or adapt tests as needed.
Add or change the documentation as needed.
Squash your commits into a single commit with git's interactive rebase. Create a new branch if necessary.
Push your branch to your fork on Github, the remote origin.
From your fork open a pull request in the correct branch. Target the project's develop branch if there is one, else go for master!
If the maintainer requests further changes just push them to your branch. The PR will be updated automatically.
Once the pull request is approved and merged you can pull the changes from upstream to your local repo and delete
your extra branch(es).
Always write your commit messages in the present tense. Your commit message should describe what the commit, when applied, does to the code โ not what you did to the code.
