Interest is the best teacher, HelloGitHub is to help you find interest!

Introduction to the

Share interesting, entry-level open source projects on GitHub.

This is a monthly magazine for people who are new to programming, passionate about programming, and interested in the open source community. The contents of the monthly include: various programming language projects, tools to make life better, books, study notes, tutorials, etc. Most of these open source projects are very easy to use, and very Cool. The main hope is for you to get your hands dirty and join the open source community.

  • Those who can program can contribute code
  • Those who cannot program can report bugs in using these tools
  • Help promote projects that you think are great
  • Star project ⭐ ️

As you browse and participate in these projects, you will learn more about programming, improve your programming skills, and find the fun of programming.

🎉 And the project HelloGitHub was born at 🎉
