Hi Georgi,
Yes, please read the documents that Visvanath recommends. Also keep contacting Giovanni with specific questions. Your scale is equal or actually smaller than each of the open universities of Asia, so I also recommend you try to contact the Moodle system admins in Turkey or Pakistan open universities. All of us in the Moodle community want to help you because you are working in Georgia, which is probably touched by the conflict in Ukraine and Russia, and maybe many refugees are there.
Best regards, Don
