I would encourage you to make use of fullPage.js instead.
Just use the parallax extension with offset 100% and place the content in the fp-bg element. You'll get exactly the same result as in pagePiling plus you'll have all the features of fullPage.js.

I'll mark it as an enhancement, but pagePiling.js is not under often development. I'll probably turn it into a fullpage.js extension. Makes it easier to maintain.

See my blog post here to get a similar result with fullpage.js:

I use pagePilling, because I need a scrollable section.

@rtemred fullpage.js provides that too. Using scrolloverflow as in this example.

@alvarotrigo oh... my bad. Thanks! I'll check it.
