+## TypeScript Usage
+
+This plugin is fully compatible with TypeScript. Here's a minimal example of how to use it with type-safe compression:
+
+```ts
+import fastify from 'fastify'
+import compress from '@fastify/compress'
+
+const app = fastify()
+
+await app.register(compress, {
+  global: true
+})
+
+app.get('/', async (req, reply): Promise<void> => {
+  const payload: string = JSON.stringify({ hello: 'world' })
+  reply.type('application/json').compress(payload)
+})
+```
