+## Style tags
+
+You can quickly stylize any string that uses html-like tags
+
+```js
+const chalk = require('chalk');
+
+const example1 = '<bold.green>Well that is <bgYellow.underline.dim.blink.black>convinient!</></>'
+const example2 = '<bold.rgb(1,4,50).underline>All functions are supported</>'
+
+console.log(chalk.parse(example1));
+console.log(chalk.parse(example2));

+- Style tags always come in pairs: An **opening tag** followed by a **closing tag**.
+- The **opening tag** name is any style/modifier that is listed above and multiple styles can be chained using a dot.
+- The **closing tag** name does not require a matching name, unlike html.
+- Styles will cascade, in other words: child tags, as well as sibling tags or text will inherit a parent tag's style.

 ## 256 and Truecolor color support
 
 Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
