-# PowerTool
 
-一堆 Minecraft 内的线上展会可能会用到的小玩意。
+Installation information
+=======
 
-Gadgets that online convention organizers may find useful when holding conventions inside Minecraft.
+This template repository can be directly cloned to get you started with a new
+mod. Simply create a new repository cloned from this one, by following the
+instructions provided by [GitHub](https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template).
 
-## 特性列表
+Once you have your clone, simply open the repository in the IDE of your choice. The usual recommendation for an IDE is either IntelliJ IDEA or Eclipse.
 
-  - 周期循环命令方块儿：按一定频率（周期）循环执行命令的命令方块。
-  - 垃圾桶：外观和原版堆肥桶一致，但丢入其中的物品会立即消失。
-  - 电源：提供任意数量的 FE 能量输出。
-  - 供货箱：创造模式下可设定其中的内容物，非创造模式下可以取出。
-  - 漏斗（装饰品）：外观和原版漏斗一致的方块，但没有任何实际功能，也没有方块实体。和原版漏斗一样可以朝四个方向旋转。
-  - 营火（装饰品）：外观和营火一致的方块，但没有任何实际功能，也没有方块实体。不能当作烟雾信号源使用。
-  - 灵魂营火（装饰品）：外观和灵魂营火一致的方块，但没有任何实际功能，也没有方块实体。不能当作烟雾信号源使用。
-  - 全息投影告示牌：和空气类似的方块，但能像告示牌一样显示文字，可以选择一定朝向玩家或者面向垂直于y轴的特定方向。创造模式下右击可打开编辑界面。
-  - 看起来没用的木棍：没有任何功能的物品，外观和原版木棍一致，但有附魔的特效。
-  - MoTD：玩家进入游戏后会收到一条聊天消息，消息内容可自定义。
-  - 栅栏绳结：原版拴绳现在可以将两根栅栏拴在一起。
-  - 更多没有方块实体的“装饰”方块
-  - 物品展示框和荧光物品展示框（但是方块版本）：可以旋转其中物品，支持红石比较器检测，支持隐藏框体。极难破坏。
-  - 透明刷：右键可直接将方块模式的展示框变为透明。
-  - 未完待续 To be continued
+If at any point you are missing libraries in your IDE, or you've run into problems you can
+run `gradlew --refresh-dependencies` to refresh the local cache. `gradlew clean` to reset everything 
+{this does not affect your code} and then start the process again.

+Mapping Names:
+============
+By default, the MDK is configured to use the official mapping names from Mojang for methods and fields 
+in the Minecraft codebase. These names are covered by a specific license. All modders should be aware of this
+license. For the latest license text, refer to the mapping file itself, or the reference copy here:
