HedgeDoc lets you create real-time collaborative markdown notes. You can test-drive
it by visiting our [HedgeDoc demo server][hedgedoc-demo].

It is inspired by Hackpad, Etherpad and similar collaborative editors. This
project originated with the team at [HackMD](https://hackmd.io) and now forked
into its own organisation. [A longer writeup can be read in the history doc](docs/history.md).
