+
+### Installation
+DynamoDB is tested on the 2 last [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 dynamodb implementation:
+```bash
+go get github.com/gofiber/storage/dynamodb
+```
+
+### Examples
+Import the storage package.
+```go
+import "github.com/gofiber/storage/dynamodb"
+```
+
+You can use the following possibilities to create a storage:
+```go
+// Initialize default config
+store := dynamodb.New()
+
+// Initialize custom config
+store := dynamodb.New(dynamodb.Config{
+	
+})
+```
+
+### Config
+```go
+type Config struct {
+
+}
+```
+
+### Default Config
+```go
+var ConfigDefault = Config{
+
+}
+```
