What is open source?

Software whose source code is released under a license in which the copyright holder grants users the rights to study, change, and distribute the software to anyone and for any purpose.

Some examples: Linux, Python, Mozilla Firefox, R, GitLab... and many more

Let's watch a video https://youtu.be/Tyd0FO0tko8

Let's not forget

• OSS is all about the people
• It is community driven for the community
• Maintainers mostly do this during their free time
• Be respectful
• Maintainers/core developers have the ultimate say in many things
• Large projects adhere to a Code of Conduct

They all roughly follow the same steps

1. Make a GitHub account
2. Choose a project and issue to work on
3. Read the contributing guidelines
4. Fork the repository (fancy word for copy)
5. Clone the copy (a.k.a download)
6. Make a branch
7. Do the work and document it
8. Test
9. Submit the work
10. Be patient (you might need to revisit some steps)
11. Your work has been accepted 🎉
