 # Redlock
 
 This is a node.js implementation of the [redlock](http://redis.io/topics/distlock) algorithm for distributed redis locks. It provides strong guarantees in both single-redis and multi-redis environments, and provides fault tolerance through use of multiple independent redis instances or clusters.
