Hello, In this short guide, I will try to jot down everything that you need to know to start contributing to open source projects.

To know if any project is open sourced or not, you need to go through the license the project has. You can know more about some standard open source licenses from here. In general, projects with the MIT license or the Unlicense have the least restrictions for you to edit, use or modify the project code.
