HedgeDoc, previously known as CodiMD, is a self-hosted, collaborative markdown editor that operates through a web interface and is open-source. It facilitates real-time collaboration on notes, diagrams, and presentations, making teamwork seamless; simply share your note link with colleagues to get started. Setting up HedgeDoc on your server is straightforward, as we offer a pre-packaged bundle and a Docker image for installation. For more information, please refer to our installation guide. The source code for HedgeDoc is hosted on GitHub and is distributed under the AGPL 3.0 license, ensuring everything remains open-source and free in terms of freedom. We encourage you to explore the code, gain insights, and contribute to its enhancement! Your suggestions and discussions are valued, and you can connect with us via our chat room on Matrix or initiate a topic on our Discourse forum. Engaging with our community will only strengthen the project further.
