 ### Instances and crashes
 
+Importing instances offers every launcher the importers read — Prism Launcher, MultiMC, PolyMC,
+ATLauncher, GDLauncher and CurseForge — whether they are installed or not, each with the folder it
+keeps its instances in on this system, Flatpak and macOS bundles included, and each with its own
+logo. Upstream listed only the launchers it found, and left the rest to a path typed in by hand.
+MultiMC keeps a plain badge instead: its branding may not be passed on.

 A running instance can be started again from the button next to Stop, as whichever account is
 selected, and the Logs tab then shows a console for each copy.
