 # local-web-server
 
-*Documentation coming soon.*
+The modular development web server for productive front-end and full-stack engineers. Use this tool to:
+
+* Help build a web application using any architecture (static website, Single Page Application with client-side rendering, dynamic app with server-side rendering, Progressive Web App etc.)
+* Prototype a web service (REST API, microservice, websocket server application etc)
+
+Agnostic which front-end framework (React, Polymer, Angular etc) you use, if any.
+
+## Synopsis
+
+This package installs the `ws` command-line tool. The most simple use case is to run `ws` without any arguments - this will host the current directory as a static web site.
+
+```sh
+$ ws
+Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
+```
+
+Being modular and extensible, there are many possibilites how to use this tool for more advanced usage.
