-This repo houses modules for use by implementations of filecoin in go.
+This repository contains modular implementations of several Filecoin subsystems. These modules are guided by the [v1.0 and 1.1 Filecoin specification updates](https://filecoin-project.github.io/specs/#intro__changelog), which separate core blockchain consensus functionality from the storage mining, storage market, and piece data transfer subsystems. 
+
+Separating an implementation into a blockchain component and one or more mining and market components presents an opportunity to encourage implementation diversity while re-using non-security-critical components, and also greatly ease miner-operator customisations.
