 # http-go-status
 
-Inspired by [httpstatu.us](https://github.com/aaronpowell/httpstatus), but written in Go, and is almost as minimal as possible. Only a signle dependency, and less than 100 lines of code in a single file.
+Inspired by [httpstatu.us](https://github.com/aaronpowell/httpstatus), but written in Go, and is as minimal as possible. No third party dependencies, and less than 100 lines of code in a single file.

+Previous versions had a single third-party dependency, but that's no longer necessary.
 
 ## Installation
 
@@ -22,8 +24,14 @@ To make your request from within a web browser (CORS is supported), you could do
 let resp = await fetch("http://localhost:8080/451");
 console.log(resp.status); // 451
 console.log(resp.statusText); // Unavailable for Legal Reasons
+
+resp = await fetch("http://localhost:8080/418/path/to/nothing");
+console.log(resp.status); // 418
+console.log(resp.statusText); // I'm a teapot
 ```
 
+If there is no path, if the first element in the path is not an integer, or if it's an integer outside of the acceptable range, a 200 will be returned.

 ## Deployment
 
 I'll leave this as an exercise for the reader.
