README

Due to the use of JSFiddle.net this presentation requires Internet connection.

Samples assume that RavenDB (Build 531) is accessible via http://localhost:8080 and is configured as follows:

<appSettings>
  <add key="Raven/AnonymousAccess" value="All"/>
  <add key="Raven/AccessControlAllowOrigin" value="*"/>
</appSettings>
