How to create a banner on NMCMS?

Question

CMS

There is cms - NMCMS, a site with parquet https://r-parket.spb.ru/ will be deployed on it. If someone suddenly dealt with this tsms, can you tell me how to make a banner on it and display it on the main page? The difficulty is that this cms has a very incomprehensible structure and try to understand what is displayed in which file. Making the banner itself is not a problem for me, but how to display it in the right place on the main page is already a problem. If you climb through the admin panel, into editing the main page, then there will be completely different content in general, which is not in sight in the frontend. Apparently, the main page is being formed somewhere else...

Answer 1

If anything, I figured out the issue: There was a commented slider in the body of the main one, then a file manager and search by code are built into the CMS itself. I drove a piece of slider code into the search, a file with a path appeared. Further, obviously, found the file, removed commenting. (Without this search, the devil will break his leg there, the structure is not the most logical)
