docs: add section on forking and cloning boilerplate code

[GideonBature]

Added a missing section to the documentation that instructs users on how to fork and clone the boilerplate code repository. The section includes a clear explanation and the necessary commands to help users get started quickly by using the provided boilerplate code. This addition enhances the user experience by providing step-by-step guidance on setting up the project environment.
