This is a live demo which uses content from Atlassian Market place status page

<style type="text/css">
.component-status {
  color:green;
  font-weight:bold;
}
</style>

It uses a bit of a custom CSS and the configuration on the page looks like this:

It all starts with Configuration definition and that looks like this:

You can see it is very simple, no authentication is used and we just read the whole page from http://status.marketplace.atlassian.com/

Then we do some "magic" with selectors to select only the bits we are interested in

And the selector for ConfiDoc Excerpt macro looks like this

div class="components-container one-column"

We just take in the contents from this "DIV" element

This is how the ConfiDoc Excerpt macro looks like in the config mode

With a bit of custom CSS we can make it more readable on our page (see live example on top of the page)
