-    You can also have a list of proxies that are rotated while searching stores. Proxies can be read from a file named `STORENAME.proxies` in the format of `socks5://username:password@ip`; one per line. In this case, there is no need to use the `PROXY_*` environments.
+    There is more information on proxy settings in the [Proxy documentation](proxy.md).

+# Proxy
+
+## Filename
+
+Proxy configuration can be set either per store in a file called `storename.proxies` or globally in `global.proxies` in the streetmerchant root directory.
+
+If both exist, the store specific file will take precedence.
+
+## Format
+
+The format is one proxy per line with the following structure:
+`protocol://[user:password@]ip[:port]`
+
+Supported protocols are `http` and `socks5`.
+
+Valid examples include:
+- `socks5://1.2.3.4:3180`
+- `socks5://abcd:[email protected]:5678`
+- `http://1.2.3.4:80`
+- `http://abcd:[email protected]:8080`
