Format guides

Markbridge converts four input formats into the same Discourse-flavored Markdown. Each guide lists the tags it supports and how they map to Markdown — pick the one that matches your source:

• BBCode — forum-classic [b]...[/b] tags, and the most feature-rich format.
• HTML — parsed tolerantly via Nokogiri.
• MediaWiki — the wikitext subset you’ll find in wiki exports.
• TextFormatter — the s9e/TextFormatter XML that phpBB 3.2+ stores.

All four feed the same renderer, so the output is consistent no matter which one you start from.
