+Pluggable Transport using WebRTC, inspired by Flashproxy.
+
+### Status
+
+- [x] Transport: Successfully connects using WebRTC.
+- [x] Rendezvous: HTTP signaling (with optional domain fronting) to the Broker
+  arranges peer-to-peer connections with multitude of volunteer "snowflakes".
+- [x] Client multiplexes remote snowflakes.
+- [x] Can browse using Tor over Snowflake.
+- [ ] Reproducible build with TBB.

 #### More Info
 
-The client uses the following `torrc` options:
+Tor can plug in the Snowflake client via a correctly configured `torrc`.
+For example:
+
 ```
 ClientTransportPlugin snowflake exec ./client \
 -url https://snowflake-reg.appspot.com/ \
 -front www.google.com \
 -ice stun:stun.l.google.com:19302

-Which allows it to speak to the Broker,
-get matched with a "snowflake" browser proxy,
-and negotiate a WebRTC PeerConnection.
+The flags `-url` and `-front` allow the Snowflake client to speak to the Broker,
+in order to get connected with some volunteer's browser proxy. `-ice` is a
+comma-separated list of ICE servers, which are required for NAT traversal.
