How do you use "grin-wallet"?

New to linux and grin.

Followed the instructions to install grin. Typing in “grin” runs grin, but when I try “grin wallet init”, it says there is a separate executable.

There is a link to a release that is a grin-wallet folder with a file. Where do I put it and what do I do with it?

And when I type in “grin-wallet init” linux says “command not found”.

What am I supposed to do to get “grin-wallet init” to work?

Install from the separate repo
