CTF-ORIONWrite lessons
A single module or a whole learning path, written with our lesson template and practice flags.
teach
Teach what you know
One lesson, a few challenges or an hour with a beginner. Everyone is welcome.
Ways to teach
Pick what suits your time and your skills. Every contribution stays free for learners.
Build challenges
File and static challenges for practice, or a set for an event. We help with testing and difficulty.
Mentor beginners
Answer questions, review writeups and help people get unstuck without handing over flags.
Translate
Bring lessons into Bangla and other languages so more people can learn in the language they think in.
Everybody is welcome to teach
You don't need a job title or a certificate. If you understand something well enough to explain it clearly, that is enough. Reviewers help shape every lesson before it goes live.
