Yeah. I'm trying to remember the syntax. I think

ref:

or

branch:

is for branch reference. So:

yaml
workspace:
    vaults:
        -
            fsPath: dependencies/github.com/<repo-path>
            remote:
                type: git
                url: git@github.com:<repo-path>
                branch: dev # This is either branch or ref for option flag
            selfContained: true

I use

branch:

in my example here, instead of

ref:

, since I saw that used in the multi-vault doc: - https://wiki.dendron.so/notes/45cfb9f2-46cf-4f67-a41e-834818fbd06e/#configuration I haven't tested! So I'd be interested in hearing how your testing goes 🙂
