When you compose a post on the EndeavourOS forums, most of the formatting you’ll need can be achieved by clicking the icons at the top of the editor window.

Don't be scared!
[details="Don't be scared!"]

I tried copying the code to a new topic on the EndeavourOS forums. The text transfers nicely, but the images don’t appear automatically, since they are coded as upload:// URLs that refer to files on the Discourse site.
