Git submodules are cool!
Modular repositories
I’ve harmonized the shortcodes for my valor and freedom themes.
This meant that I’d prefer to have them both reference the same ones and keep in sync with each other.
I found out that I could use submodules to modularize the projects. Now instead of trying to manage the hugo shortcodes in both locations I have a single shortcodes repository that both (and upcoming) themes will reference.
