## Common questions

### How do I configure Tor to use Snowflake?

Add the appropriate Bridge and ClientTransportPlugin lines to your torrc file. The client README explains building and running the Snowflake client.

### Can I run a Snowflake proxy without setting up a server?

Yes, the easiest option is to install the Snowflake browser addon, enable it, and keep it running. A blocked user can connect when the icon turns green.

### Do Tor Browser, Orbot, or Ricochet-Refresh need a separate Snowflake installation?

No, Snowflake comes embedded in those Tor-powered apps. If one of them cannot connect to the Tor network, you can use the built-in Snowflake to unblock it.

### What level of traffic does a standalone Snowflake proxy often see?

One operator reported running about 30 Dockerized Snowflake proxies on different IP addresses. Each proxy generally saw about 360-400 connections per hour and about 1 GB per hour.

### How do Snowflake clients find volunteer proxies?

Tor clients automatically find available browser proxies via the Broker, the domain fronted signaling channel. The client and proxy then establish a WebRTC peer connection.
