Right now the documentation for this plugin is pretty lacking, until that is fixed the best example on how to use the plugin is to look at how it is used in unexpected.
```js helloWorld() ```
If you expect the example to fail, you can follow the code block with an expected output block:
```output Error: Silence this is a library! ```
There are a few things you can achieve more then what is explained above, like async examples with promises and skiping examples for different environments or just skipping evaluation altogether. For now you'll have to look at how unexpected does it to learn the ticks.
