What I have currently is the following:

# No Match Deployments
# In order to use these deployments with Fabrikate, follow the steps below.
# 1. Add the source (git repository link)
# 2. Add a path field (path within the git repository) ex: "path: stable/"
# 3. Specify helm for applications generated using a Helm chart ex: "type: helm"
# Otherwise, comment them out to prevent errors with Fabrikate generation.
# See here for Fabrikate steps: https://github.com/Microsoft/fabrikate
- name: spring-boot-api
  source: <source repository url>
  method: git
- name: spring-boot-ui 
  source: <source repository url>
  method: git

I think this should be sufficient information to help edit the generated component.yaml. What does everyone think?

@andrewDoing not sure if we want to get too far into specifics here, but there's now also resources on how to deploy from private repositories: https://github.com/microsoft/fabrikate/blob/master/docs/auth.md

And you could add a direct link to the Component docs: https://github.com/microsoft/fabrikate/blob/master/docs/component.md
