For instructions on how to use the Membase Web Console to manage your Membase Server installation, see Membase Web Console.
If you already have an application that uses the Memcached protocol then you can start using your Membase Server immediately. If so, you can simply point your application to this server like you would any other memcached server. No code changes or special libraries are needed, and the application will behave exactly as it would against a standard memcached server. Without the client knowing anything about it, the data is being replicated, persisted, and the cluster can be expanded or contracted completely transparently.
If you do not already have an application, then you should investigate one of the available Membase client libraries to connect to your server and start storing and retrieving information. For more information, see Couchbase SDKs.
