+
+A fast and minimal alternative to globby and fast-glob, meant to behave the same way.
+
+Both globby and fast-glob present some behavior no other globbing lib has,
+which makes it hard to manually replace with something smaller and better.
+
+This library uses only two subdependencies, compared to `globby`'s [23](https://npmgraph.js.org/?q=globby@16.2.0)
+and `fast-glob`'s [17](https://npmgraph.js.org/?q=fast-glob@3.3.3).
+
+## Usage
+
+```js
+import { glob, globSync } from 'tinyglobby';
+
+await glob(['files/*.ts', '!**/*.d.ts'], { cwd: 'src' });
+globSync('src/**/*.ts', { ignore: '**/*.d.ts' });
+```
