set up git submodules

bash

git submodule add <link>

when cloning first time, you can do git clone <link> --recurse-submodules
or if you already cloned and you forgot, you can do git submodule update --init
if you change something in the submodule, just commit and push it, then commit and push main repo.

vs code recently-ish (2021) added a gui for submodules so handling them is pretty ok now.

updating a submodule:

bash

git submodule update --remote

otherwise it's just going to try and checkout the revs defined in .gitmodules
