"Recipes" generally follow on from each other. I.e., if a particular recipe requires a mail server, that mail server would have been described in an earlier recipe.
Each recipe contains enough detail in a single page to take a project from start to completion.
When there are optional add-ons/integrations possible to a project (i.e., the addition of "smart LED bulbs" to Home Assistant), this will be reflected either as a brief "Chef's note" after the recipe, or if they're substantial enough, as a sub-page of the main project
When creating swarm networks, we always explicitly set the subnet in the overlay network, to avoid potential conflicts (which docker won't prevent, but which will generate errors) (https://github.com/moby/moby/issues/26912)
