 ## Usage
 
 ```swift
-let app = HBApplication()
-// run response compression on application thread pool when buffer is 
-// larger than 32768 bytes otherwise run it on the eventloop
-app.addResponseCompression(execute: .onThreadPool(threshold: 32768))
-// run request decompression on eventloop with no limit to the size
-// of data that can be decompressed
-app.addRequestDecompression(execute: .onEventLoop, limit: .none)
+let router = Router()
+router.middlewares.add(RequestDecompressionMiddleware())
+router.middlewares.add(ResponseCompressionMiddleware(minimumResponseSizeToCompress: 512))
 ```
 
-Adding request decompression means when a request comes in with header `content-encoding` set to `gzip` or `deflate` the server will attempt to decompress the request body. Adding response compression means when a request comes in with header `accept-encoding` set to `gzip` or `deflate` the server will compression the response body.
