+- [Signatures](#signatures)
+- [Examples](#examples)
+
+### Signatures
+```go
+func HTTPHandlerFunc(h http.HandlerFunc) fiber.Handler
+func HTTPHandler(h http.Handler) fiber.Handler
+```
+
+### Example
+Import the adaptor package that is part of the Fiber web framework
+```go
+import (
+    "net/http"
+    
+	"github.com/gofiber/fiber/v2"
+	"github.com/gofiber/fiber/v2/middleware/adaptor"
+)
+```
+
+After you initiate your Fiber app, you can use the following possibilities:
+```go
+func main() {
+	app := fiber.New()
+
+	// http.Handler -> fiber.Handler
+	app.Get("/", adaptor.HTTPHandler(handler(greet)))
+
+	// http.HandlerFunc -> fiber.Handler
+	app.Get("/func", adaptor.HTTPHandlerFunc(greet))
+
+	log.Fatal(app.Listen(":3000"))
+}
+
+func handler(f http.HandlerFunc) http.Handler {
+	return http.HandlerFunc(f)
+}
+
+func greet(w http.ResponseWriter, r *http.Request) {
+	fmt.Fprint(w, "Hello World!")
+}
+```
