Module Chapters and Out of the Abyss

I am just starting out and am using Princes  of the Apocalypse as a way to learn how this all works. I am starching with Level 1 chanters so I am trying to find the cheaper six pages is there a way to figure out what pages go with what chapters? I would also like to see a roll 20 version of Out of the Abyss.  

As good a story as PoTA is, it is a mess when you're looking for info. Here is a list of stuff I found when I was running it the first time: <a href="http://detectmagic.blogspot.com/2015/04/ref-sheet-for-princes-of-apocalypse.html" rel="nofollow">http://detectmagic.blogspot.com/2015/04/ref-sheet-for-princes-of-apocalypse.html</a> <a href="http://thecampaign20xx.blogspot.com/2015/04/elemental-evil-guide-to-princes-of.html?m=1" rel="nofollow">http://thecampaign20xx.blogspot.com/2015/04/elemental-evil-guide-to-princes-of.html?m=1</a> <a href="https://www.reddit.com/r/dndnext/comments/36vwdy/princes_of_the_apocalypse_resources/" rel="nofollow">https://www.reddit.com/r/dndnext/comments/36vwdy/princes_of_the_apocalypse_resources/</a> <a href="https://slyflourish.com/tying_the_threads_of_princes.html" rel="nofollow">https://slyflourish.com/tying_the_threads_of_princes.html</a>
