+### Wbenv command reference
+
+`wbenv` (**W**ire**b**ird **env**ironment) command is a shell wrapper
+that is included with `wirebird-client` package, allowing to run a Node.js script
+with `WIREBIRD` and `NODE_OPTIONS` variables set.
+
+Syntax:
+
+```sh
+wbenv [-h wirebird_host] {ui|curl|pretty} <command>
+```
+
+Examples:
+
+```sh
+wbenv ui npm start                  #runs `npm start` logging HTTP requests with Wirebird
+wbenv ui yarn add -D @types/react   #runs `yarn add -D @types/react` logging HTTP requests with Wirebird (cool, eh?)
+wbenv -h http://192.168.88.1:4380 ui node app.js
