Qualified uses a slightly customized form of Github-Flavored Markdown for editing challenge instructions.

Multi-Language Support

In addition to GFM, which already provides support for fenced code blocks, we also support providing examples in multiple languages. Simply stack fenced code blocks back to back. The languages that are not relevant to the context will be filtered out. You can use the language tabs at the top of the preview pane to set the language display context.
