Fork the project. Before you start working on a task, fork the project. This will create a copy of the project that you can work on without affecting the main project.
Create a branch. Create a new branch for the task you are working on. This will allow you to isolate your changes from the main project.
Make your changes. Make your changes to the code and test them thoroughly.
Commit your changes. Once you are happy with your changes, commit them to your branch.
