What you're having a problem with, and what kind of trouble you're having. For instance, "My router crashes when I'm trying to update Bazzite. Help?" That way, people who actually know something about the topic are more likely to view your post.
Also, use the spacebar and don't abbreviate unnecessarily. The person who can help you might have English as their third or fourth language, and have a hard time decoding run-together gobbledegook.
Anyway, there are plenty of examples already in the community. It's often wise to check around to see how other people are doing things before you speak up.
