Warren Keller has written a great guide to PI. See here
https://www.bintel.com.au/product/in...xinsight-book/ it is also available as a Kindle book if preferred. I used it on Kindle at first but then got the hard copy as easy to sit and read while processing.
It will at least get you started and on your way to processing. The Light Vortex online tutes are also great but I always prefer a book!!
It will take a while but once you start to to "get" PI, it can make your images sing.
