 [English](README_en.md)
 
 ## 简介
 
-
+Tiny Plane是一个固定翼小飞机飞控项目，旨在DIY一款操控良好、飞行时间长、可玩性高的固定翼小飞机。目前基于48cm翼展手抛机进行改装，飞控采用ESP32-C3。
 
 ## 特性
 
+飞控主要特性：
+
+- 单串锂电池供电，最大工作电压5.5V
+- 电源电压、电流感测
+- 锂电池温度感测
+- DCDC降压电源，效率90%以上
+- 3轴加速度计，3轴陀螺仪
+- 气压计，高度精度10cm
+- 2路动力电机通道，支持电流感测
+- 2路数字IO通道
+- USB TypeC接口，调试和烧写程序
+- 1路串口，可用于连接GPS
+
+机身主要特性：
+
+![手抛机机身](img/手抛机.jpg)
+
+- 49cm翼展，47cm长，22cm平尾
+- 重量 ~40g
+
+## 硬件
+
+改装主要涉及3个方面：
+
+1. 加装马达
+2. 加装电池
+3. 加装飞控
+
+更好的操控性能还需要加装舵机，目前尚未加装。
+
+### 加装马达
+
+采用2个720空心杯电机配合55mm桨后推方案，为此设计了马达安装座：
+
+![马达安装座](img/马达座-1.jpg)
+
+加装在机翼后缘：
+
+![加装马达](img/马达座-2.jpg)
+
+### 加装电池和飞控
+
+电池和飞控板需要较大的安装空间，为此设计了一个座舱，将电池和飞控板安装在座舱内：
+
+![电池和电路板座](img/电路板座.gif)
+
+这个安装座下面固定飞控电路板，上面装电池：

 [中文](README.md)
 
 ## Introduction
 
-
+Tiny Plane is a fixed-wing aircraft flight control project aimed at DIY enthusiasts who want to build a well-controlled, long-flight-time, and highly playable fixed-wing aircraft. Currently, it is based on a 48cm wingspan hand-launched glider and uses the ESP32-C3 flight controller.
 
 ## Features
 
-### Overview
+Main features of the flight controller:
+
+- Powered by a single-cell lithium battery with a maximum operating voltage of 5.5V
+- Power voltage and current sensing
+- Lithium battery temperature sensing
+- DCDC buck power supply with an efficiency of over 90%
+- 3-axis accelerometer and 3-axis gyroscope
+- Barometer for altitude measurement with an accuracy of 10cm
+- 2 channels for motor control with current sensing
+- 2 channels for digital input/output
+- USB Type-C interface for debugging and programming
+- 1 serial port for connecting GPS
+
+Main features of the airframe:
+
+![Hand-launched glider](img/手抛机.jpg)
+
+- 49cm wingspan, 47cm length, 22cm tail
+- Weight ~40g
+
+## Hardware
+
+The modifications mainly involve three aspects:
+
+1. Adding motors
+2. Adding batteries
+3. Adding flight controllers
+
+To achieve better control performance, it is recommended to add servos, which have not been installed yet.
+
+### Adding Motors
+
+Two 720 hollow cup motors are used in conjunction with 55mm propellers for rearward thrust. A motor installation seat is designed for this purpose:
+
+![Motor installation seat](img/马达座-1.jpg)
+
+Installed on the trailing edge of the wing:
+
+![Adding motors](img/马达座-2.jpg)
+
+### Adding Batteries and Flight Controllers
+
+The batteries and flight controller board require a larger installation space. Therefore, a cabin is designed to accommodate the batteries and flight controller board:
+
+![Battery and circuit board seat](img/电路板座.gif)
+
+The flight controller circuit board is fixed below this seat, and the battery is placed on top:
