+
+### Installation
+
+```bash
+go mod init github.com/<user>/<repo>
+```
+
+And then install the Cloudflare KV implementation:
+
+```bash
+go get github.com/gofiber/storage/cloudflarekv
+```
+
+### Examples
+
+Import the storage package.
+
+```go
+import "github.com/gofiber/storage/cloudflarekv"
+```
+
+You can use the following methods to create storage. The Key must be an API Token generated with at least `Account.Workers KV Storage` permission. Check the [Create API Token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/) documentation to generate one.
+
+```go
+// Initialize default config
+store := cloudflarekv.New()
+
+store := cloudflarekv.New(cloudflarekv.Config{
+    Key: "",
+    Email: "",
+    AccountID: "fiber",
+    NamespaceID: "fiber",
+    Reset: false,
+})
+
+```
+
+### Config
+
+```go
+type Config struct {
+
+	// Cloudflare Auth Token
+	//
+	// Optional. Default is ""
+	Key string
+
+	// Cloudflare Email
+	//
+	// Optional. Default is ""
+	Email string
+
+	// Account id
+	//
+	// Optional. Default is "fiber"
+	AccountID string
+
+	// Namespace id
+	//
+	// Optional. Default is "fiber"
+	NamespaceID string
+
+	// Reset clears any existing keys in existing Table
+	//
+	// Optional. Default is false
+	Reset bool
+}
+```
+
+### Default Config
+
+```go
+var ConfigDefault = Config{
+	Key:         "",
+	Email:       "",
+	AccountID:   "fiber",
+	NamespaceID: "fiber",
+	Reset:       false,
+}
+```
