+## Proxy Usage
+
+Making your REST calls via a proxy is now supported by the Snowflake REST SQL Connector. To make it easy to do so we have introduced the **ProxySettings** entity. To use a proxy do the following: 
+
+1. Create a **ProxySettings** object
+2. Set the `Host` and `Port` attributes to the host of the proxy and the Port the proxy is listening on
+3. Optional: Set the `User` and `Password` to authenticate against your proxy
+4. Associate the **ProxySettings** to your **ConnectionDetails** object when using the **POST_v1_ExecuteStatement** operation or the **CortexConnection** when using the **CortexAnalyst** operation
+
+Once configured, the connector automatically detects the **ProxySettings** object and routes REST requests through the specified proxy.
