How to format your forum posts

The Docker forum is using Discourse, which supports several ways to format your posts: Markdown; see commonmark.org/help for an interactive tutorial BBCode A small selection of HTML Any combination of the above Blank lines for formatting and readability Quite often you’ll need an empty line above specific formatting to make it work.

In short: Use code blocks, not quotes, especiially for yaml codes. Thank you.
