+# Super Metroid
+
+## Where is the settings page?
+
+The [player settings page for this game](../player-settings) contains all the options you need to configure and export a
+config file.
+
+## What does randomization do to this game?
+
+Items which the player would normally acquire throughout the game have been moved around. Logic remains, so the game is
+always able to be completed, but because of the item shuffle the player may need to access certain areas before they
+would in the vanilla game.
+
+## What items and locations get shuffled?
+
+All power-ups and ammunition can be shuffled, and all locations in the game which could contain any of those items may
+have their contents changed.
+
+## Which items can be in another player's world?
+
+Any of the items which can be shuffled may also be placed into another player's world. It is possible to choose to limit
+certain items to your own world.
+
+## What does another world's item look like in Super Metroid?
+
+A unique item sprite has been added to the game to represent items belonging to another world.
+
+## When the player receives an item, what happens?
+
+When the player receives an item, a text box will appear to show which item was received, and from whom.
