Question:
One day I went to clone a library on github and there was an instruction for us to use the git submodule update command.
I've been working with git for some time and until then I wasn't aware of this command.
What is this submodule command for?
Answer:
This command is useful when you want to insert another git repository into your main project (a library, for example).
For git the submodule will be a fully independent project. You can edit the content below the submodule folder, commit, push, etc. As long as you have permission to do so 🙂
There are alternatives, such as package managers, that organize dependencies in other, more efficient and secure ways.
