How does one install this?

[qazip]

Both aurora store and yalp store are not working for me so I came across this software. How does one install apkgrabber so I can install an app from google-play?

APKGrabber is for updates, it ain't no Play Store / any store replacement.

There's a new fork for yalp in fdroid. You can download directly from here -https://f-droid.org/en/packages/com.github.kiliakin.yalpstore/

The issues I had such as not being able to view apps from same developer as an app I've got downloaded have been fixed. Seems much more stable than the original yalp.
