+		<p class="mt-2 text-xs text-text-secondary leading-relaxed">
+			Every player starts at 1000 ELO. Win a match to gain points, lose to drop.
+			The system uses K=32, so new players' ratings shift quickly. As you play more,
+			your rating stabilizes around your true skill level. Queue matchmaking pairs players
+			with similar ELO for fair matches.
