 For production deployment Apache (or other webservers like nginx, lighttpd etc.) should be used.
 
 For Apache a sample configuration is provided in the folder `apache` which can be adapted.
+
+Please keep in mind that you may have to adjust the path to the sound files in your apache config in order to enable local playback on the clients.
+
+Usage
+=====
+
+Users can browse the webinterface, search for sounds and play them on the remote server or their local browser.
+
+Additionally to the normal point and click usage there are also several keyboard shortcuts available.
+
+Keyboard shortcuts
+------------------
+
+- Navigation items, input fields and sound buttons can be selected by using tab and shift+tab
+- esc clears the search field
+- enter plays the selected sound
+- ctrl+k and ctrl+c kill all sounds
+- ctrl+x switches between local and remote playback
+- ctrl+enter kills sounds before the selected gets played
+
+
+Live version
+============
+
+A list of sound requests and already added sounds can be found here: https://pad.wiai.de/p/soundboardTodos
