I’ve inherited a Hugo project at work that uses the DocuAPI theme. I want to update it, but I don’t know how and I can’t find any instructions on either the Hugo documentation or in this repository on how to do it.

So, how does one install or update this theme?

In the project, I find a themes/DocuAPI directory that looks like it is a different (read: much older) version of the same files contained within this repository at the root level (i.e. there are archetypes and assets directories, etc.). However, just downloading a copy of this repository’s contents and replacing the directory in the project just breaks the project build (with Error: module "github.com/slatedocs/slate" not found; either add it as a Hugo Module or store it in "/src/themes".: module does not exist) and it’s not clear what the issue really is. It sounds like a dependency issue, but since there are no instructions on how to install dependencies, I turn in circles.

Furthermore, I can’t find any information as to which version of the theme I’m using in the project right now. That prevents me from looking at the release log and updating in small steps in order to take care of any breaking changes that might’ve happened along the way.
