+### Using an upstream proxy for federation
+
+Add the following to your `dev.secret.exs` or `prod.secret.exs` if you want to proxify all http requests that pleroma makes to an upstream proxy server:
+
+    config :pleroma, :http,
+      proxy_url: "127.0.0.1:8123"
+
+This is useful for running pleroma inside Tor or i2p.
