Tip: You can have your profile updated automatically during the gameplay! Please take a look on the
list of tools using Inara API that will do that for you.

Please note that the updates are not realtime and may happen just on certain events like a session start, FSD jumps, dockings in stations, etc.
The ship configuration is imported automatically via journals or Inara API and represents the actual ship configuration in the game. The alternate/secondary ship configurations may be imported from Coriolis or EDShipyard. When no actual ship configuration is present, the alternate ship configuration is displayed instead of it.
