+IPFS
+=====
+
+[IPFS](https://ipfs.io) is a global, versioned, peer-to-peer filesystem. It combines good ideas from previous systems such Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single bittorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built in. You can also mount the world at /ipfs.
+
+Introduction
+------------
+
+This chart bootstraps IPFS deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+
+Configuration
+-------------
+
+The following table lists the configurable parameters of the IPFS chart and their default values.
+
