+# KeyCommand
+
+本模组允许玩家自定义一个按键并且绑定一个命令.
+
+需要在服务端也安装本模组 并且只有服务端也有**完全一样**的自定义命令时才能执行命令.
+
+当玩家处在多人游戏时,执行的命令无视玩家是否有op,只要服务端允许 可以执行玩家本不能执行的命令.
+
+当玩家处在单机模式时,能执行的命令由玩家本身权限决定.
+
+***
+
+This mod allows players to customize a key and bind a command.
+
+This mod needs to be installed on both side and only the server side also has 
+**Exactly The Same** command key bind, it can be executed.
+
+When the player is in a multiplayer game,
+the executed command ignores whether the player has op or not, as long as the server allows it to execute commands that the player cannot execute.
+
+When the player is in single player game,the commands can be executed or not are determined by the player's own authority.
