Such as:
When does it crash: Is it random, or when you click something specific, like "Multiplayer"?
What happens when it crashes: Instant crash to desktop, error code, or other?
Having that error code makes it easier to find a fix.
Also remember to read the "Read Me" file that is downloaded with the mod.
