+# Battle
+
+> A simple but exciting fun game for you to play with your friends.
+
+## About
+
+Except server management, we also provide a small amount of fun commands. You can set them up in your server to increase diversity of events.
+
+## Quick Setup
+
+Pretty easy, you just need to setup:
+
+- Manager Role (optional): Basically event manager. They can start and clear a game without fulfilling the `Manage Guild` default permission requirement, they can also participate in a game.
+- Game Channel (required): People cannot play this game outside of this channel.
+- Access Role (required): Participants will be granted this role to access the game channel.
+
+Don't forget to configure permission overwrites in the game channel properly.
+
+```py
+              View Channel  Send Messages
+Default          true          false
+Manager Role     true          true
+Access Role      true          true
+```
+
+## Start a new game
+
+You can start a game with `[p]battle start` and tell your friends how to play by showing the `[p]battle` embed. Each game cannot have less than 2 participants or have more than 30 participants. Access role will be assigned after starting a new game and channel permission overwrites will also be changed, both will be done automatically.
+
+## Cancel or clear a game
+
+You can cancel a currently active game or clear a previously ended game by running `[p]battle clear`, access role will not be removed automatically if you suddenly cancel a currently active game.
