+### Signatures
+```go
+func New(config ...Config) Storage
+func (s *Storage) Get(key string) ([]byte, error)
+func (s *Storage) Set(key string, val []byte, exp time.Duration) error
+func (s *Storage) Delete(key string) error
+func (s *Storage) Reset() error
+func (s *Storage) Close() error
+```
+### 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 default config
+store := arangodb.New()
+
+// Initialize custom config
+store := arangodb.New(arangodb.Config{
+	Host:       "http://127.0.0.1",
+	Port:       8529,
+	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
+
+	// Port where the DB is listening on
+	//
+	// Optional. Default is 8529
+	Port int
+
+	// Server username
+	//
+	// Optional. Default is ""
+	Username string
+
+	// Server password
+	//
+	// Optional. Default is ""
+	Password string
+
+	// Database name
+	//
+	// Optional. Default is "fiber"
+	Database string
+
+	// Collection name
+	//
+	// Optional. Default is "fiber_storage"
+	Collection string
+
+	// Reset clears any existing keys in existing collection
+	//
+	// Optional. Default is false
+	Reset bool
+	// Time before deleting expired keys
+	//
+	// Optional. Default is 10 * time.Second
+	GCInterval time.Duration
+}
+```
+
+### Default Config
+Used only for optional fields
+```go
+var ConfigDefault = Config{
+	Host:       "http://127.0.0.1",
+	Port:       8529,
+	Database:   "fiber",
+	Collection: "fiber_storage",
+	Reset:      false,
+	GCInterval: 10 * time.Second,
+}
