What's wrong?

What's the correct behavior?
follow document, install command is npm install @vulcan-sql/cli, but it will install in local place.
But usage command is vulcan init, if modules install in local node_modules, command is npx vulcan init or write usage command in package.json.
And this project look like a sub-project control tool. Suggest install command modify to npm install -g @vulcan-sql/cli, it will make usage command right.
