+# Hollow Knight
+
+## 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?
+
+Randomization swaps around the locations of items. The items being swapped around are chosen within your YAML.
+Shop costs are presently always randomized.
+
+## What Hollow Knight items can appear in other players' worlds?
+
+This is dependent entirely upon your YAML settings. Some examples include: charms, grubs, lifeblood cocoons, geo, etc.
+
+## What does another world's item look like in Hollow Knight?
+
+When the Hollow Knight player picks up an item from a location and it is an item for another game it will appear in that
+player's recent items display as an item being sent to another player. If the item is for another Hollow Knight player
+then the sprite will be that of the item's original sprite. If the item belongs to a player that is not playing Hollow
+Knight then the sprite will be the Archipelago logo.

+# Hollow Knight for Archipelago Setup Guide
+
+## Required Software
+* Download and unzip the Scarab Mod Manager from the [Scarab GitHub Releases page](https://github.com/fifty-six/Scarab/releases).
+* A legal copy of Hollow Knight, not purchased or played through XBox Game Pass.
+    * Unfortunately, the Game Pass version is not currently compatible with mods.
+
+## Installing the Archipelago Mod using Scarab
+1. Launch Scarab and ensure it locates your Hollow Knight installation directory.
+2. Click the "Install" checkbox near the "Archipelago" mod entry.
+3. Launch the game, you're all set!
+
+## Configuring your YAML File
+### What is a YAML and why do I need one?
+You can see the [basic multiworld setup guide](/tutorial/Archipelago/setup/en) here on the Archipelago website to learn 
+about why Archipelago uses YAML files and what they're for.
+
+### Where do I get a YAML?
+You can use the [game settings page for Hollow Knight](/games/Hollow%20Knight/player-settings) here on the Archipelago 
+website to generate a YAML using a graphical interface.
+
+### Joining an Archipelago Game in Hollow Knight
+1. Start the game after installing all necessary mods.
+2. Create a **new save game.**
+3. Select the **Archipelago** game mode from the mode selection screen.
+4. Enter the correct settings for your Archipelago server.
+5. Hit **Start** to begin the game. The game will stall for a few seconds while it does all item placements.
+6. The game will immediately drop you into the randomized game. 
+   * If you are waiting for a countdown then wait for it to lapse before hitting Start.
+   * Or hit Start then pause the game once you're in it.
