Split Rail is the thin bar at the very bottom of a TaylorURL site's footer. On the left it says "Built by TaylorURL" and links to [taylorurl.com](https://www.taylorurl.com). On the right it has a Status link to the [status page](https://www.taylorurl.com/status), the site's version and the year.
Each site installs it as a dependency instead of keeping its own copy, so a change here reaches every site when it bumps the version.
-## What it does
+## How it works
-- Picks up its colors from the footer it sits in, so it works on light and dark footers
-- Shows the version you pass in, and the current year
-- Gives the links bigger tap targets on touch screens
-- Ships as plain JavaScript with no JSX, so it works in Vite, Create React App and Next.js without extra setup
-- Has no dependencies apart from React 17 or later
+One file, `src/index.js`. It uses `createElement` instead of JSX so it runs untranspiled in Vite, Create React App and Next.js. The only peer dependency is React 17 or later.
