HackMD is a realtime collaborative markdown notes on all platforms.
Inspired by Hackpad, but more focusing on speed and flexibility.
Still in early stage, feel free to fork or contribute to this.
Thanks for your using! 😄

- npm and bower
- Download a release and unzip or clone into a directory
- Enter the directory and type
npm install && bower install, will install all the dependencies - Install PostgreSQL and MongoDB (yes, currently we need both)
- Import database schema, see more on below
- Setup the configs, see more on below
- Setup environment variables, which will overwrite the configs
- Run the server as you like (node, forever, pm2)
The notes are store in PostgreSQL, the schema is in the hackmd_schema.sql
To import the sql file in PostgreSQL, see http://www.postgresql.org/docs/9.4/static/backup-dump.html
The users, temps and sessions are store in MongoDB, which don't need schema, so just make sure you have the correct connection string.

From 0.3.2, we start support operational transformation.
Which make concurrent editing safe and not break up other users' operations.
Even more, now can show other clients' selections.
