# Step template for creating a GitHub App token via Azure Key Vault.
# This template can be used in release jobs where checkout is not available.
# The CLI script from microsoft/create-github-app-token-via-key-vault is inlined below.
# The token is created and stored in an Azure Pipelines variable (default: GH_TOKEN).
# A revocation step runs at the end with condition: always().
# To use the token, add your steps between this template's create and revoke steps
# by setting insertSteps.
