 This package provides the following middleware:
 
-#### 1. Compression Middleware
+#### Compression Middleware
 
 Applies Gzip or Brotli compression to HTTP responses based on client support. This reduces the size of the response payload and enhances load times.
 
 **Ideal For**: Large JSON responses, static files, or data-intensive endpoints.
 
+> [!WARNING]
+> When using Brotli, a client-side decoding error may occur with non-secure connections, as modern browsers generally support Brotli compression only over HTTPS.
