+这个文件是帮助您使用本例程。
+在这里简略的描述本工程的使用：
+
+1.基本信息：
+本例程用于测试或者演示RP2040-Zero上WS2812B;
+
+2.管脚连接：
+管脚连接你可以在RP2040-Zero.py查看，这里也再重述一次：
+DIN    ->    16
+
+3.基本使用：
+    1): 按住RP2040-Zero板上的Boot按键，将RP2040-Zero通过Type-C USB线接到电脑的USB接口，然后松开按键。
+        接入之后，电脑会自动识别到一个可移动盘（RPI-RP2）
+        
+    2): 将Python目录下的uf2文件夹中rp2-pico-20210902-v1.17.uf2 文件复制到识别的可移动盘（RPI-RP2）中
+    
+    3): 更新Thonny IDE
+        sudo apt upgrade thonny
+        
+    4): 打开Thonny IDE （点击树莓logo -> Programming -> Thonny Python IDE ）
+        选择Tools -> Options... -> Interpreter
+        选择MicroPython(Raspberry Pi Pico 和ttyACM0端口
+        
+    5): 在Thonny IDE中打开Python/RP2040-Zero.py文件
+        然后运行当前脚本（绿色小三角）即可
+

+This file is to help you use this routine.
+Here is a brief description of the use of this project:
+
+1. Basic information:
+This routine is used to test or demonstrate WS2812B on RP2040-Zero.
+
+2. Pin connection:
+You can check the pin connection at RP2040-Zero.py, and repeat it here:
+DIN    ->    16
+
+3. Basic use:
+    1): Press and hold the Bootsel button on the RP2040-Zero board, connect RP2040-Zero to the USB port of the 
+        computer through the Type-C USB cable, and then release the button.
+        After connecting, the computer will automatically recognize a removable disk (RPI-RP2)
+        
+    2): Copy the rp2-Pico-20210902-v1.17.uf2 file from the Uf2 folder in the Python directory to an identified 
+        removable disk (rpi-rp2)
+    
+    3): Update Thonny IDE
+        sudo apt upgrade thonny
+        
+    4): Open Thonny IDE （Click raspberry logo -> Programming -> Thonny Python IDE ）
+        select Tools -> Options... -> Interpreter
+        select MicroPython(Raspberry Pi Pico  and ttyACM0 port
+        
+    5): Open the Python/ rp2040-zero.py file in Thonny IDE
+        Then run the current script (little green triangle)
