+## Usage
+
+Add the `Default` middleware for basic security measures.
+
+```go
+s := gin.New()
+s.Use(helmet.Default())
+```
+
+You can also add each middleware separately:
+
+```go
+s.Use(helmet.NoCache())
+```
+
+Those not included in the `Default()` middleware are considered more advanced and require consideration before using.
+
+See the [godoc](https://godoc.org/github.com/danielkov/gin-helmet) for more info and examples.
