Introducing HedgeDoc, the digital garden where your markdown ideas bloom collaboratively! Formerly strutting the internet as CodiMD, this open-source marvel transforms your browser into a hive of real-time, co-authored brilliance. Picture this: you're crafting notes, spinning graphs, and conjuring presentations with the ease of a wizard, while your team hops onto your note-link like it's the hottest party in cyberspace. And where does this shindig take place? Right on your own digital turf, because HedgeDoc keeps your data snug as a bug on your server. But wait, there's more! Slide into presentation mode and watch your markdown morph into a visual feast, or dabble with a smorgasbord of graphs, diagrams, and multimedia magic. Fear not the power-hungry permissions ogre, for HedgeDoc tames it with a slick system that's easier to manage than your coffee order. And if you ever have a 'whoopsie-daisy' moment, just time-travel back to a happier version of your notes. The cherry on top? This feature-stuffed firecracker runs smoother than a greased otter on hardware as humble as a Raspberry Pi. Host it on RepoCloud, and you'll be saving more coins than a level of Super Mario, all while basking in the glory of open-source camaraderie!
