+### NOTES
+
+- Each lua plugin gets its own lua state and will run in a goroutine.<br/>
+- Lua plugins will not go through a proxy if they are not instructed to do so. If you are using the provided http module, you can set the proxy value before loading the http module as provided in the examples under `plugins`. The module will read and set the following environment variables in the order given:
+  - `ALL_PROXY`
+  - `HTTPS_PROXY`
+  - `HTTP_PROXY`
+  - `https_proxy`
+  - `http_proxy`
+
+  `http` and `socks5` proxies are supported. unfortunately, the `socks5h` proxy is not supported.<br/>
+
+```sh
+ALL_PROXY=socks5://172.17.0.1:9050
