PIO and Github Library Download

I’m new to PlatformIO, Visual Studio, and Github. I need some guidance on how to download a library to my PIO project. My board is a ESP32 DEV and I want to include this library in the build: GitHub - arduino-libraries/NTPClient: Connect to a NTP server
Any help would be appreciated.

That library is available already in PlatformIO. If you go here: PlatformIO Registry you will find details on installing using pio lib install ... or using lib_deps in the platformio.ini file. Also, a list of the header files required to be #included and some examples of using the library.

You can search for libraries at PlatformIO Registry for particular frameworks etc.
