Built by devs, for devs 💡

Remember that one person in class who took amazing notes that saved your life before exams? This is the digital, community-driven version of that.

We can all learn from each other, so there is clearly an added value in these notes being shared and editable by everyone. By having the community improve and create new content this would massively make everyone's educational IT journey a lot better.

Whether you're prepping for interviews, learning something new, or quickly refreshing your memory on an old concept — this is your go-to reference hub.

Every topic aims to be as clear and concise as possible. Many come with quizzes, cheatsheets, and community-curated explanations to help you master them faster.

The content is fully open and editable — built by the community, improved by the community. Join in and help shape the learning experience for others!

Let the journey begin!
