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 1.15+
- 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
