Working with Hugo themes you probably use git submodules. These are basically subrepositories within your repository. They can be used for several different reasons, but the main one is probably so you can download updates.
You also need a submodule theme to be able to host on Netlify.
Execute this in your root folder to add the theme to the theme folder.
git submodule add https://github.com/name/my-theme.git themes/my-theme
You also need to configure the
config.toml file to be able to use the theme.
theme = "my-theme"
If you want to download the latest release of the theme to your Hugo site, you can to that with this command.
git submodule update --remote --merge
You also need to add, commit and push to changes in your main Hugo repo for them to work.
git clone your Hugo repo on a new computer, you won’t get the theme because it is a submodule. You can download it by executing this command in your root folder:
git submodule update --init --recursive
