Clone git repo with submodules

I’m using hugo-paper as my blog theme. To avoid manually cloning theme files it’s recommended to install it via git submodule by using this command:

git submodule add https://github.com/nanxiaobei/hugo-paper themes/paper

But if you will forget to pull submodule with your blog theme on freshly cloned repo, hugo will welcome us with this error message:

WARN 2023/06/26 22:07:33 found no layout file for "HTML" for kind "home": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.

Our submodule needs to be pulled as well, we can do that by using this command:

git submodule update --init --recursive

Nice! Now we pulled our submodules as well. But what if we want to update our theme?

git submodule update --remote

Now we only need to commit this change (since now our submodule points to latest commit)
