CodiMD was recently renamed from its former name was HackMD. CodiMD is the free software version of HackMD. It was the original Version of HackMD. The HackMD team initiated CodiMD and provided a solid code base. Due to the need of paying bills, A fork was created and called HackMD EE, which is a SaaS (Software as a Service) product available at [hackmd.io](https://hackmd.io).
We decided to change the name to break the confusion between HackMD and CodiMD, formally known as HackMD CE, as it never was an open core project.
Just to more confusion: We are still friends with HackMD :heart:
*For the whole renaming story, see the [related issue](https://github.com/hackmdio/hackmd/issues/720)*
- npm (and its dependencies, especially [uWebSockets](https://github.com/uWebSockets/uWebSockets#nodejs-developers), [node-gyp](https://github.com/nodejs/node-gyp#installation))
-`libssl-dev` for building scrypt (see [here](https://github.com/ml1nk/node-scrypt/blob/master/README.md#installation-instructions) for further information)
2. Enter the directory and type `bin/setup`, which will install npm dependencies and create configs. The setup script is written in Bash, you would need bash as a prerequisite.

We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current `config.json.example` and check the warnings on startup.
