How to load the PWM.h library into the IDE

[servicejb]

Hello All. I am a former IT developer but new to Arduino. I am running the Arduino IDE v2.3.4. I am trying to load the PWM.h library into the IDE but cannot figure out how to do it. I downloaded what I think are the correct files from:
https://code.google.com/archive/p/arduino-pwm-frequency-library/downloads

I have a zip file, but I cannot find any information on how to get that into the IDE.
Can someone point me to instructions on how to do this so I can #include the PWM.h library in my code.

Many thanks.

Libraries - Arduino Reference

Or in the IDE 1.8.19 use Tools>Manage Libraries

Thanks @jremington . The instructions in Arduino Reference worked (as expected). However, I had to delete two folders from the downloaded file to get the library installed. The original download from Google had two folders in it that were preventing the library from installing. One was PWM_lib_example and the other was PWM_lib_resolution_example. When I deleted these two folders, the library was successfully installed in the IDE. (I hope I did not mess anything up by deleting those folders.)
Thanks for pointing me to the documentation and for the quick reply.

(I hope I did not mess anything up by deleting those folders.)

They might provide useful example code, so it may be worth looking at the contents.

The library source code folder is the most important.
