+The `checkMatch` property takes a [glob pattern](https://www.npmjs.com/package/glob) — or an array of glob patterns — to match files inside your
+project structure that contain instances of a Check, i.e. `**/__checks__/*.check.ts`. Use an array when you need to match multiple file extensions or directories, e.g. `["**/*.check.ts", "**/*.check.js"]`.
 
 The goal of this property is so you can add files to an existing repo that are automatically detected. This pattern should be very familiar to unit testing: the test runner takes
 care of finding, building and running all the files.
