Overview
Welcome to the 3rd ROOT Hackathon event, which will take place at CERN's IdeaSquare: the Innovation Space of the Lab!
This edition, The Fixathon 2.0, will take place over two days and will focus on refining ROOT through small but impactful improvements.
During the event we will focus on:
- 🐞 Small Bug Density issues: addressing well-scoped issues that improve the everyday ROOT experience
- 📚 Documentation improvements: writing or improving tutorials, examples, and documentation pages
How to participate
Do you have a small ROOT issue that has been on your mind?
Report it → Tag it → Join us to work on it!
The ROOT Team will be driving the effort, but as demonstrated in previous Hackathons, the input and participation of ROOT users in invaluable for our open-source project. So if you ever wanted to contribute to ROOT but never knew where to start, join us and start right here!
