+## HTML Template
+
+Use [standard Golang http templates](https://golang.org/pkg/html/template/) to render response page.
+
+For example, you have a template file `index.html` in `templates` directory:
+
+```html
+{{.Name}}
+```
+
+Fill the context and provide a path to the template file:
+
+```go
+func(req *express.Request, res *express.Response){
+ type TmplContext struct{
+ Name string
+ }
+ data := TmplContext{"Rob"}
+ res.Render("template.html", &data)
+}
+```

## Safe Cleanup on exit
Newer version of goexpress provides three new methods namely `express.ShutdownTimeout`, `express.BeforeShutdown` and `express.Shutdown`, these methods can be utilised to do cleanup before the server shuts down.
