The guide lived one directory above the repo, so the README links were
broken on GitHub. It also described the old layout: parsers inside
index.php, a copied <style> block, and div-based tables. It now covers
parsers/{name}.php, emailShell(), esc(), real table markup,
case-insensitive headers, and local testing with a sendmail override.
