## PlatformIO Quick Start
1. Install [Visual Studio Code](https://code.visualstudio.com/) and [Python](https://www.python.org/)
2. Search for the `PlatformIO` plugin in the `Visual Studio Code` extension and install it.
3. After the installation is complete, you need to restart `Visual Studio Code`
4. After restarting `Visual Studio Code`, select `File` in the upper left corner of `Visual Studio Code` -> `Open Folder` -> select the `LilyGo-LoRa-Series` directory
5. Wait for the installation of third-party dependent libraries to complete
6. Click on the `platformio.ini` file, and in the `platformio` column
7. Select the board name you want to use in `default_envs` and uncomment it.
8. Uncomment one of the lines `src_dir = xxxx` to make sure only one line works , Please note the example comments, indicating what works and what does not.
9. Click the (✔) symbol in the lower left corner to compile
10. Connect the board to the computer USB-C , Micro-USB is used for module firmware upgrade
11. Click (→) to upload firmware
12. Click (plug symbol) to monitor serial output
13. If it cannot be written, or the USB device keeps flashing, please check the **FAQ** below
## Arduino IDE quick start
1. Install [Arduino IDE](https://www.arduino.cc/en/software)
2. Install [Arduino ESP32](https://docs.espressif.com/projects/arduino-esp32/en/latest/)
3. Copy all folders in the `lib` directory to the `Sketchbook location` directory. How to find the location of your own libraries, [please see here](https://support.arduino.cc/hc/en-us/articles/4415103213714-Find-sketches-libraries-board-cores-and-other-files-on-your-computer)
* Windows: `C:\Users\{username}\Documents\Arduino`
* macOS: `/Users/{username}/Documents/Arduino`
* Linux: `/home/{username}/Arduino`
4. Open the corresponding example
* Open the downloaded `LilyGo-LoRa-Series`
* Open `examples`
* Select the sample file and open the file ending with `ino`
5. On Arduino ISelect the corresponding board in the DE tool project and click on the corresponding option in the list below to select
