About this site
Chalkline is an independent guide to American football in the UK. It was written for curious readers who want a clear place to begin.
What this site is
Think of this as a small editorial project built around five guides: the rules of the game, positions and gear, how competition is organized in the UK, the sport's history in Britain, and a beginner's path into playing. The goal is simple, plain explanation for readers who have never played a down.
What it is not
This site is not a team, a league, a governing body or a broadcaster, and it has no affiliation with any of them. You will not find rosters, scores, schedules or ticket details here. Nothing on these pages speaks for an official organization.
How the guides are written
Every guide sticks to well-established facts: how the game is built, dates that are widely documented, and the general outline of the British competition system. When something changes from one season to the next, such as league divisions, the guides say so and send readers to the official sources run by the governing bodies and by college sport.
A note on accuracy
Rules differ slightly between the NFL, college football and amateur competitions, and each club sets its own practical arrangements. Use these guides as an introduction, and confirm details with the right organization or club before you act on them.
