+### Installation
+ArangoDB is tested on the 2 last (1.14/1.15) [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
+```bash
+go mod init github.com/<user>/<repo>
+```
+And then install the mysql implementation:
+```bash
+go get github.com/gofiber/storage/arangodb
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/arangodb"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize custom config
+// *http* is mandatory
+store := arangodb.New(arangodb.Config{
+	Host:            "http://127.0.0.1",
+	Port:            "8529",
+    Username:        "username",
+    Password:        "password"
+	Database:        "fiber",
+	Collection:      "fiber_storage",
+	Reset:           false,
+	GCInterval:      10 * time.Second,
+})
+```
+
+### Config
+```go
+type Config struct {
+	// Host name where the DB is hosted
+	//
+	// Optional. Default is "http://127.0.0.1"
+	Host string
