Bulma css module required by hugo-fresh theme is not found

Thank you for the reply. I did
hugo mod init github.com/mikemitchellwebdev/janeausten250

There is no output in the folder.
Question 1: Should there be a go.mod file after running hugo mod init? There is no output in the folder. I’m using go.1.22.

Question 2

I found a thread (Error: module "github.com/hugo-mods/release-notify" not found) which linked to an example config.yaml

module:
imports:

Following that example, I created a config.yaml manually and put this in it

module:
imports:

running hugo server

Error: command error: failed to load modules: module “GitHub - jgthms/bulma: Modern CSS framework based on Flexbox” not found in “/Users/mm/janeausten250/themes/github.com/jgthms/bulma”; either add it as a Hugo Module or store it in “/Users/mm/janeausten250/themes”.: module does not exist

Question 3: How do I add bulma as a module?

Thank you
