 ### Basic
 You have to create a renderer (`ascii`) and let it render the desired string through the `Render` method. After that you can simply print the returned string.
 ```go
+import "github.com/probandula/figlet4go"

+// ...

 ascii := figlet4go.NewAsciiRender()
 
+// The underscore would be an error
 renderStr, _ := ascii.Render("Hello World")
 fmt.Print(renderStr)
 ```

 ### Colored
 The colors given in the `[]color.Attribute` slice are repeating if the string is longer than the slice. You have to call the `RenderOpts` instead of the `Render` method to give the Renderer the Options.
 ```go
+import "github.com/probandula/figlet4go"
+import "github.com/fatih/color"

 ascii := figlet4go.NewAsciiRender()
