Capella & Arcadia getting start

I will start with Capella modeler and I search informations on several topics :

  • even if the capella website gives download page to take tools, can you tell me how to get Arcadia additionals ?
    Or is it included in Capella package ?
  • is it exist some documents or websites to get start with Capella tools for system engineering ?
    If yes links can be given ?
