Sourcing
Hi again, QuartixRu. You'll have noticed that I've undone a number of your recent edits, due to insufficient sourcing. Wikipedia depends on the core principle of WP:Verifiability: all assertions must be verifiable by content in a published, independent, reliable, secondary source. You could start with Help:Referencing for beginners. Mathglot (talk) 08:52, 10 December 2023 (UTC)
