Error when building a new site with Academic theme

I just created a new site using hugo new site command. Then I added the Academic theme manually (which means I downloaded ZIP from https://github.com/wowchemy/starter-academic, unzipped the file into the theme folder, and inserted theme = "academic" in config.toml). However, when I ran hugo server, there was an error:

Error building site: “…\themes\academic\content\home\demo.md:76:1”: failed to extract shortcode: template for shortcode “callout” not found

My hugo version is v0.78.2/extended windows/amd64. How can I fix that?

Many thanks to all of you.

You probably have to run another command before running hugo itself to download dependencies, but I don’t know which one.
