+The Native SDK allows the configuration of an `HTTP` (`CONNECT`) or `SOCKS5` proxy through which requests can be tunneled to our backend. It can be configured via the following option interface:
 
 ```c
 sentry_options_t *options = sentry_options_new();
-sentry_options_set_http_proxy(options, "http://my.proxy:10010");
+sentry_options_set_proxy(options, "http://my.proxy:8080");
 sentry_init(options);
 
 /* ... */
 ```
+The same function can also be used for the `SOCKS5` proxy:
+```c
+sentry_options_t *options = sentry_options_new();
+sentry_options_set_proxy(options, "socks5://my.proxy:1080");
+sentry_init(options);
+
+/* ... */
+```
+
+
+We support `HTTP` proxies on all platforms, and `SOCKS5` proxies on Linux and macOS. Depending on the platform, the transport provides a fallback in case the proxy is not reachabled. The following table shows the expected behaviour.
