Running a Google Search for Basic Meditation brings many results, a few of which I scanned. This one:

Mindfulness: Getting Started - Mindful

seems accessible, easy to follow with the relevant information and has a very good Walk Through of a Breathing Meditation, a starting point for any beginner.

I would look around your area of the Ukraine for Meditation Classes. I am a firm believer that guidance at the beginning leads to good Practice and less frustration.
