 ## Developing the website
 
-A static version of the website can be generated by running `sbt web-stage`.  This will output the entire website to the `target/web/stage` directory.  You should start a simple HTTP server from here to serve the docs, eg using `python -m SimpleHTTPServer`.  The `sbt ~web-stage` command can be used to tell sbt to watch for changes and rebuild the site whenever anything changes.

The `sbt ~web-stage` command can be used to tell sbt to watch for changes and rebuild the site whenever anything changes.
 
 For convenience, `sbt run` does the above for you, starting a static Akka HTTP server in the stage directory, and then watching the filesystem for changes and rebuilding the site whenever it changes.
