Introduction
What Selection Room is, who it is for, and how the docs are organized.
Selection Room is a transparent College Football Playoff selection simulator. It builds a composite ranking from public inputs, selects a 12-team field under the published 5+7 rules, seeds a bracket, and shows its work at every step. The live site is at www.selectionroom.org.
Two ways to use it
Browse the hosted site (no install). Everything on selectionroom.org is open: pick a run from the header switcher, then explore the Dashboard, Rankings, Bubble, Bracket, Validation, and Scenario Lab. Signing in with GitHub lets you launch your own live runs.
Run it locally or contribute. The whole project is open source: a Python engine plus this Next.js app. Start at Getting started and Local development.
