It's got the kitchen sink included. Tried to install everything the average user would need but that does not guarantee it will have 'everything' you would need.
The channel list is already installed for UK. So basically it is ready to run but might need updating or you can use Autobouquets to get the latest UK settings installed. All installed and just the touch of a button away.
If you are using a fixed dish and want to use it for UK then there is nothing more you need to do. If you are going motorised then you will need to set the motor config up.
