+# A Hat in Time
+
+## Where is the options page?
+
+The [player options page for this game](../player-options) 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. 
+Chapter costs are randomized in a progressive order based on your options, 
+so for example you could go to Subcon Forest -> Battle of the Birds -> Alpine Skyline, etc. in that order. 
+If act shuffle is turned on, the levels and Time Rifts in these chapters will be randomized as well.
+ 
+To unlock and access a chapter's Time Rift in act shuffle, 
+the levels in place of the original acts required to unlock the Time Rift in the vanilla game must be completed, 
+and then you must enter a level that allows you to access that Time Rift. 
+For example, Time Rift: Bazaar requires Heating Up Mafia Town to be completed in the vanilla game. 
+To unlock this Time Rift in act shuffle (and therefore the level it contains) 
+you must complete the level that was shuffled in place of Heating Up Mafia Town 
+and then enter the Time Rift through a Mafia Town level.
+
+## What items and locations get shuffled?
+
+Time Pieces, Relics, Yarn, Badges, and most other items are shuffled. 
+Unlike in the vanilla game, yarn is typeless, and hats will be automatically stitched 
+in a set order once you gather enough yarn for each hat. 
+Hats can also optionally be shuffled as individual items instead. 
+Any items in the world, shops, act completions, 
+and optionally storybook pages or Death Wish contracts are locations.
+
+Any freestanding items that are considered to be progression or useful 
+will have a rainbow streak particle attached to them. 
+Filler items will have a white glow attached to them instead.
+
+## 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 A Hat in Time?
+
+Items belonging to other worlds are represented by a badge with the Archipelago logo on it.
+
+## When the player receives an item, what happens?
+
+When the player receives an item, it will play the item collect effect and information about the item 
+will be printed on the screen and in the in-game developer console.
+
+## Is the DLC required to play A Hat in Time in Archipelago?
+
+No, the DLC expansions are not required to play. Their content can be enabled through certain options 
+that are disabled by default, but please don't turn them on if you don't own the respective DLC.
