HackMD 0.3.2

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! 😄

Operational Transformation

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.
See more at http://operational-transformation.github.io/

Database dependency

• PostgreSQL 9.3.6 or 9.4.1
• MongoDB 3.0.2

Import database schema

The notes are store in PostgreSQL, the schema is in the hackmd_schema.sql
To import the sql file in PostgreSQL, type psql -i hackmd_schema.sql

The users, temps and sessions are store in MongoDB, which don't need schema, so just make sure you have the correct connection string.
