-## Setup
+## Examples
 
-First import the middleware from Fiber,
+Import the middleware package that is part of the Fiber web framework
-
-import (
-  "github.com/gofiber/fiber/v2"
-  "github.com/gofiber/fiber/v2/middleware/cache"
-)
-
-Then create a Fiber app with `app := fiber.New()`.
-
-## Minimum Config
 
 ```go
-// `Key` must be a 32 character string. It's used to encrpyt the values, so make sure it is random and keep it secret.
+import (
-// You can call `encryptcookie.GenerateKey()` to create a random key for you.
+  "github.com/gofiber/fiber/v2"
-// Make sure not to set `Key` to `encryptcookie.GenerateKey()` because that will create a new key every run.
+  "github.com/gofiber/fiber/v2/middleware/encryptcookie"
+)
+```
+
+After you initiate your Fiber app, you can use the following possibilities:
+
+```go
+// Default middleware config
 app.Use(encryptcookie.New(encryptcookie.Config{
     Key: "secret-thirty-2-character-string",
 }))
+
+// Get / reading out the encrypted cookie
+app.Get("/", func(c *fiber.Ctx) error {
+    return c.SendString("value=" + c.Cookies("test"))
+})
+
+// Post / create the encrypted cookie
+app.Post("/", func(c *fiber.Ctx) error {
+    c.Cookie(&fiber.Cookie{
