-## 描述
+## Description
 
-**Neoflash HAT** 是一款专为M5SticKC设计的矩阵RGB LED灯板.这块尺寸面积仅有58x23.5mm的PCB板总共嵌入了126颗可编程RGB LED灯，除了实现一般的灯光效果以外，高密度矩阵设计的它还可以作为一个小型点阵LED显示屏使用.
+**NeoFlash HAT** is specifically designed for M5StickC, it an RGB LED matrix.  Space on PCB board is 58x23.5mm and total include 126 RGB LEDs. Every single RGB LED is programmable, which allows you setting the colors and brightness, plus on the 7*18 matrix layout, you will have a nice experience on either display digital numbers or colorful light effection. 
 
-在使用灯板制作一些数据显示应用时，使用配套的黑茶色亚克力板，能够有效增强显示效果.结合配套与默认的两组弯曲排针，**Neoflash HAT**能够以两种角度安装到M5StickC上.如果你打算为你的项目添加一个精致小巧的LED矩阵屏幕的话，Neoflash HAT 会是一个不错的选择.
+We even prepared a dark brown acrylic board to cover on the NeoFlash board for better effection. We also provide two types of pin set with a 90-degree bend so that you can attach the NeoFlash board onto M5StickC in different ways. 
+If you thinking about adding a display on your project, NeoFlash is a good choice.
