+Decompress middleware decompresses HTTP request if Content-Encoding header is set to gzip.
+*Please note: The body will be decompressed in memory and consume it for the lifetime of the request (and garbage collection). 
+
+*Usage*
+
+`e.Use(middleware.Decompress())`
+
+## Custom Configuration
+
+*Usage*
+
+```go
+e := echo.New()
+e.Use(middleware.DecompressWithConfig(middleware.DecompressConfig{
+  Skipper: Skipper
+}))
+```
+
+## Configuration
+
+```go
+DecompressConfig struct {
+  // Skipper defines a function to skip middleware.
+  Skipper Skipper
+}
+```
+
+*Default Configuration*
+
+```go
+DefaultDecompressConfig = DecompressConfig{
+  Skipper: DefaultSkipper,
+}
+```
