Thank you. I've tried to download and run Zapstore on Linux over the CLI, but it keeps giving an error "command not found," and the documentation is not very clear on how to troubleshoot such errors.
Could you please offer a guide on how to use Zapstore? We could chat over Nostr or any platform of choice.
You could as well drop a guide here. Any which way you are cool with would work.
