+## Can I make my GoToSocial instance use a proxy (http, https, socks5) for outgoing requests?
+
+Yes! GoToSocial supports canonical environment variables for doing this: `HTTP_PROXY`, `HTTPS_PROXY` and `NO_PROXY` (or the lowercase versions thereof). `HTTPS_PROXY` takes precedence over `HTTP_PROXY` for https requests.
