# This config file was created for myself (@janlay). You may want to add or remove some rules to make efficient use of the Internet. 

# This file depends on the main.conf which defines your own proxy.
# Your main.conf will look like this:
# ---- START ----
# #!PROXY-OVERRIDE:rules.conf
# [Proxy]
# Proxy = https,server.address,port,username,password
# ---- END ----
