How to learn to program based on 1C-Bitrix?

Question

CMS

Hello.
Until recently, I was engaged only in Front-end development.
Now I decided that it's time to climb into the Back-end.
As I understand it, the most popular CMS today is 1C-Bitrix.
But she's paid!
Question:
- how to proceed and where to start studying Back-end development based on this CMS?
- where to find lessons, exactly lessons and not API documentation?
- it's paid, how to learn, can you even download it and put it on a virtual host?
I understand that you first need to know PHP and SQL (php seems to be a regular OOP language, and the documentation is good, I studied C # at the university, so it has a lot in common with PHP, I also know SQL, I wrote a server client for WIndows, I can make multi-level queries)
PS: I spent 2 weeks on MODX (I didn’t write my own snippets, of course, I used all the standard tools (display articles, organize menus, pull up a template), in general, in order to understand what CMS is, I decided to try it)
I myself haven’t googled anything about Bitrix, not I want to step on a rake, I want to listen to experienced people in this matter, and go right away, though not expensive, but at least in the right direction in studying)
Thank you in advance for your help!

Why do you need a back end? continue to develop in the front, become a specialist, and not a dude who knows everything a little.
