Understanding Projects
Understanding of project like how folders are arranged? how files are linked? which tech stack is used? is the most important thing before raising an issue or making a pull request in any project on GitHub. //

Making Pull Request
Your PR should do one thing. Always make a pull request for one part or section so that it would be easier for reviewers and maintainers to merge your pull request. If you are solving multiple issues in a project then open multiple PRs.
