+This is a custom HTML render to support multi templates, ie. more than one `*template.Template`.
+
+
+
+#Simple example
+
+```go
+package main
+
+import (
+    "html/template"
+
+    "github.com/gin-gonic/gin"
+    "github.com/gin-gonic/contrib/renders/multitemplate"
+)
+
+func main() {
+    router := gin.Default()
+    router.HTMLRender = createMyRender()
+    router.GET("/", func(c *gin.Context) {
+        c.HTML(200, "index", data)
+    })
+    router.Run(":8080")
+}
+
+func createMyRender() multitemplate.Render {
+    r := multitemplate.New()
+    r.AddFromFiles("index", "base.html", "base.html")
+    r.AddFromFiles("article", "base.html", "article.html")
+    r.AddFromFiles("login", "base.html", "login.html")
+    r.AddFromFiles("dashboard", "base.html", "dashboard.html")
+
+    return r
+}
+```
