Weather Underground Github Integration on Home Assistant OS?

Hey everybody! Im trying to install this addon: cytech/Home-Assistant-wundergroundpws: Home Assistant custom component sensor for Weather Underground personal weather station users (github.com): to access my Weather Underground PWS, the documentation states that I should go to my .homeassistant folder, on Home Assistant OS (what im using) were and how would I find this folder?
Or is there a different better solution to get my PWS data to Home Assistant?

You can use the samba addon to access your folders via Windows or Mac. After you are able to access your folders, copy the wundergroundpws folder and content to the \config\custom_components folder. After that just follow the guidelines on GitHub. Good luck!
