This is what a new player is greeted with upon selecting 'Game Guide' and choosing 'Beginners' guide.'
"Welcome to Gielinor. The second you step onto the island of Ashdale, you'll be met by Gudrik. Be sure to complete his tutorial - it's quick, introduces you to the game's interface, and demonstrates the key concepts of RuneScape. Plus, you get to defeat an evil necromancer and nick her hat. Read on for a handy guide to your first few days in game, and beyond."
At the minimum, it should now say something about tutorial island.
