CodiMD lets you collaborate in real-time with markdown.
Built on [HackMD](https://hackmd.io) source code, CodiMD lets you host and control your team's content with speed and ease.
## CodiMD - The Open Source HackMD
[HackMD](https://hackmd.io) helps developers write better documents and build active communities with open collaboration.
HackMD is built with one promise - **You own and control all your content**:
- You should be able to easily [download all your online content at once](https://hackmd.io/c/news/%2Fs%2Fr1cx3a3SE).
- Your content formatting should be portable as well. (That's why we choose [markdown](https://hackmd.io/features#Typography).)
- You should be able to control your content's presentation with HTML, [slide mode](https://hackmd.io/p/slide-example), or [book mode](https://hackmd.io/c/book-example/).
With the same promise of you owning your content, CodiMD is the free software version of [HackMD](https://hackmd.io), developed and opened source by the HackMD team with reduced features, so you can use CodiMD for your community and own your data. *(See the [origin of the name CodiMD](https://github.com/hackmdio/hackmd/issues/720).)*
CodiMD is perfect for open communities, while HackMD emphasizes on permission and access controls for commercial use cases.
HackMD team is committed to keep CodiMD open source. All contributions are welcome!
