How to change Dark Souls tutorial and controls to a keyboard

I'll start off by pointing out that the Graveyard you find near the start of the game is intended for a higher level player, so you should avoid it for now.

Both the Cleric and the Warrior are excellent beginner classes. The Cleric has healing, which is very helpful, but has very weak armor. The Warrior lacks healing, but has more well rounded stats for combat, and starts with better equipment.

When it comes to developing your character, there is one thing you should keep in mind: You should only boost one offensive stat. This includes: Strength, Dexterity, Intelligence and Faith. The reason for this is that most weapons have stat scaling. So if you have a weapon which scales with strength, and you decided to split your points between dexterity and strength, all of the points invested in dexterity are essentially useless. That isn't to say you shouldn't put any points into the other offensive stats, just that you should only be putting enough to meet stat requirements for equipment.

My personal suggestion would be to focus on a Dexterity build. This will allow you to use bows effectively, which can make your game a lot easier. Bows allow you to both kill and weaken enemies from afar, lure single enemies away from a group, and take care of archers as soon as you encounter them.

In the Main Menu, go to:

Settings > Gameplay > Controls

then change the Input Device to Keyboard.

If you still see the Xbox controller options in the menus and not the keyboard controls, you need to unplug any game controllers from your PC before booting the game (Joysticks, etc).
