An example WordPress repository with a workflow script that installs Git submodules.

The workflow does the following:

1. Checkout the repository
2. Tells the checkout task to fetch submodules with submodules: true
3. Provides a personal access token to access the private repo token: ${{ secrets.REPO_PAT }}. (see below)
4. Create a build artifact with name wpcom which is required for WordPress.com's GitHub Deployment feature

Note: if you have submodules are in a private repo, you will need to create a personal access token and then save that token as a secret in the repo where the workflow runs.

1. Create a classic token here https://github.com/settings/tokens
   • Choose repo scope
2. Go to https://github.com/:account/:repo/settings/secrets/actions and save the token with a name like REPO_PAT.
3. In your workflow file, include token: ${{ secrets.REPO_PAT }} on the checkout action. See here.
