-Template plugin for Fastify
+Templates rendering plugin support for Fastify.
 
+`point-of-view` decorates the reply interface with the `view` method for manage view engines that can be used to render templates responses.
+
+Currently supports the following templates engines:
+- [`ejs`](http://www.embeddedjs.com/)
+- [`pug`](https://pugjs.org/api/getting-started.html)
+- [`handlebars`](http://handlebarsjs.com/)
+
+In `production` mode, `point-of-view` will heavily cache the templates file and functions, while in `development` will reload every time the template file and function.
 ## Install
