+Write [Snabbdom](https://github.com/paldepind/snabbdom) virtual DOM with [Babel's JSX](http://babeljs.io/docs/advanced/transformers/other/react/).
 
+Snabbdom is a small Virtual DOM library. Unlike React, it's not a fully opinionated framework, but just focuses on the core virtual DOM problem : construct virtual DOM trees (virtual nodes) and patch the real DOM with them. When those operations happen is entirely up to you. The main benefit is that you can adopt whatver architdectural UI pattern you like in your application.
+
+Babel is JavaScript compiler that converts ES2015 (modern JavaScript) into compatible JavaScript (ES5) code. A nice feature of Babel is that it supports [React JSX syntax](http://facebook.github.io/react/docs/displaying-data.html#jsx-syntax) and in the same time allows you to take the result of this JSX (attributes + body) and do wharever you like with it. Snabbdom-jsx transforms this JSX data into snabbdom virtual nodes. 
+
 Features:
 
-- Transform Babel JSX templates to Snabbdom virtual nodes
+- Transforms Babel JSX templates into Snabbdom virtual nodes
 - Straightforward mapping from JSX attributes to Snabbdom data attributes using namespaces 
-- JSX Components are simples functions `(attributes, children) => vnode`. No more messy classes.

-If you're wondering how Components would fit in a large application, you can look into the [todomvc example](https://github.com/yelouafi/snabbdom-jsx/tree/master/examples/todomvc).

+As in React, note that all components must start with a capital letter, while regular HTML tags start with lower case letters. This the way Babel also distinguish component invocation from simple tag creation. 
+
+Perhaps of less obvious utility, but instead of a function, a component can also be an object with a `view` function; i added this in order to support nesting in UI patterns; especially in the Elm architecture, where a component is an object with a `view` function (among others)
+
+for example you can have a `Task` component
+
+
+```js
+Task.view = ({task}) => ...
+Task.update = ...
+```
