This library must work with Heltec ESP32 develop framework! A detail document about how to install Heltec ESP32 development framework and this library available here:
https://heltec-automation-docs.readthedocs.io/en/latest/esp32/quick_start.html
We recommend using the Arduino library manager, it's the simplest way
Open Arduino IDE, then Select Sketch->Include Library->Manage Libraries...
Search Heltec ESP32 and install it.
Firstly, make sure git and the Arduino IDE have been installed first. If not, please refer How to install Git and Arduino. When Arduino is installed correctly, you will find a folder in "Username/Documents/Arduino/Library". this library must in this path!
Open "Git bash" in path Username/Documents/Arduino/Library, and input:
git clone https://github.com/HelTecAutomation/Heltec_ESP32.git
You will see such a new folder in your library path, install done.
This library requires the Heltec ESP32 develop framework!
A detailed step by step instructions to execute some examples available here:

If there is a "Limited" folder in the resources page, it means the product have limited resources that not public by default, refer to this document to download: Get Limited Technical Resources.
Please make sure use a high-quality Micro USB cable, it will reduce many problems.
这个Arduino库必须配合Heltec ESP32编译环境一起使用！完整的“编译环境 + 库”的的教程可以参考这里：
https://heltec-automation-docs.readthedocs.io/en/latest/esp32/quick_start.html
强烈推荐使用Arduino自带的“库管理器”进行安装!
打开Arduino IDE, 选择项目->加载库->管理库...，打开“库管理器”
搜索Heltec ESP32并安装.
*首先,请确保Git和Arduino IDE都已经正确安装。如果没有，请参考这里的安装方法怎样安装Git和Arduino IDE。 *
强调一下：这个库的路径必须位于操作系统的“文档/Arduino/libraries”文件夹内！！！文档文件夹是操作系统自带的，必须！必须！必须！
在“文档/Arduino/libraries”路径下打开"Git bash"，输入:
git clone https://github.com/HelTecAutomation/Heltec_ESP32.git
如果一切正常，应该是这样的
