+
+ChessCraft is a Paper plugin that adds in-world chess matches against other players and chess engines.
+With ChessCraft, players can challenge each other to intense chess battles in a Minecraft environment.
+
+## Features
+
+- In-world chess matches, reminiscent of life-size chess boards.
+- Pieces: Supports both custom models through a resource pack (linked below), and using textured player heads for resource pack free use.
+- Automatic downloading of the correct Stockfish (chess engine powering ChessCraft) executable for your platform.
+
+## Download
+
+Downloads can be obtained from the [releases](https://github.com/jpenilla/chesscraft/releases) section.

+
+## Installation
+
+To install ChessCraft, simply drop the plugin into your Paper server's `plugins` folder.
+The configuration can be adjusted at `plugins/ChessCraft/config.yml`.
+
+By default, ChessCraft will be configured for use with a resource pack containing custom models for chess pieces.
+It can be downloaded [here](https://github.com/jpenilla/chesscraft/raw/master/resources/ChessCraft_Resource_Pack.zip). You can either have your players manually install it, or set it as your server resource pack/merge its contents into your existing server resource pack.
+
+## Usage
+
+First, you must create a chessboard by standing at the desired location for the southwest corner of the board and using the `/chess create_board <board_name> <facing>` command.
+
+Then, use the `/chess challenge player|cpu` commands to challenge an opponent. That's all! Now you can right-click the pieces to start making moves!
+
+Chess boards will not automatically place or remove blocks from the world (besides the pieces if configured to use block pieces), they will only manage pieces. This is to allow
+building your chess board in any way you like. However, the `/chess set_checkerboard` command can be used to automatically place blocks for a standard board.
