+**In the near future, the api will be something like:**
 
+```
+var proxy = require("foxy");
+                    // target               // proxy url
+proxy.createServer("http://localsite.dev", "http://localhost:5000");

+Built-in middleware will re-write html on the fly to update any urls & there'll also be the option
+for additional rules for the re-writing.
+
+###Todo
+
+- [x] websocket support
+- [ ] accept a url for target
+- [ ] test the shit out of the link re-writing
