+This is a standalone (not browser-based) version of the Snowflake proxy. For browser-based versions of the Snowflake proxy, see https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake-webext.
+
+### Dependencies
+
+- Go 1.13+
+- We use the [pion/webrtc](https://github.com/pion/webrtc) library for WebRTC communication with Snowflake proxies. Note: running `go get` will fetch this dependency automatically during the build process.
+
+### Building the standalone Snowflake proxy
+
+To build the Snowflake proxy, make sure you are in the `proxy/` directory, and then run:
+
+```
+go get
+go build
+```
+
+### Running a standalone Snowflake proxy
+
+The Snowflake proxy can be run with the following options:
+```
+Usage of ./proxy:
+  -broker string
+        broker URL (default "https://snowflake-broker.bamsoftware.com/")
+  -capacity uint
+        maximum concurrent clients
+  -keep-local-addresses
+        keep local LAN address ICE candidates
+  -log string
+        log filename
+  -relay string
+        websocket relay URL (default "wss://snowflake.bamsoftware.com/")
+  -stun string
+        stun URL (default "stun:stun.stunprotocol.org:3478")
+  -unsafe-logging
+        prevent logs from being scrubbed
+```
