Following the instructions on this page using go1.16 windows/amd64 to install Ebiten doesn't work.
Trying to execute the following command
go run -tags=example github.com/hajimehoshi/ebiten/v2/examples/rotate

Yields the following result:

no required module provides package github.com/hajimehoshi/ebiten/v2/examples/rotate; to add it:
        go get github.com/hajimehoshi/ebiten/v2/examples/rotate

Attempting to perform the command as instructed then yields this result:

go get github.com/hajimehoshi/ebiten/v2/examples/rotate
