While drafting an operations manual for a customer, we realized that we don't really have for the platform administrator a page which describes the "forest" before describing the "trees". This PR bridges this gap.

Great work, added some nits and a few comments.
Something I am missing is perhaps to mention that Welkin apps is built on Helmfile and that our configuration files are used to configure the Helm charts that we have as part of our Helmfile stack(s).
