How to Install Vuestorefront v1

I want to install Vuestorefront Version 1. I got this command "npx @vue-storefront/cli generate store" from the official document. I installed VSF by using the given command but it's installed v2.6.14.
I didn't get any document for version 1.
Is there any document to install VSF version 1 ?
