Every pilot-facing download lives in the Crew Center at /crew-center/downloads — categorised by Software, Liveries, Sceneries, Tools and Documents.
Each entry shows description, version, file size and (where relevant) the aircraft type. Filter pills at the top help you narrow down by category.
Liveries usually ship as ZIP — extract into Community/ (MSFS) or the matching add-on folder (P3D/X-Plane). StarlingPulse has its own page with changelog and setup guide.
