-## Test Plugin
+## Example usage
 
-The parameters of the plugin enabled above indicate that only one concurrent 
request is allowed. When more than one concurrent request is received, will 
return `503` directly.
+The example above configures the Plugin to only allow one concurrent request. 
When more that one request is received, the Plugin will respond with a 503 
status code:
 
 ```shell
 curl -i http://127.0.0.1:9080/index.html?sleep=20 &
 
 curl -i http://127.0.0.1:9080/index.html?sleep=20
+```

Review Comment:
   I agree with Zhiyuan, `shell` is not recognized by the renderer used by the 
Docusauraus, although it is supported in GitHub. Refer 
https://github.com/FormidableLabs/prism-react-renderer/blob/master/src/vendor/prism/includeLangs.js#L8
 and 
https://github.com/github/linguist/blob/master/lib/linguist/languages.yml#L5837.
 Use `bash` instead.
