A proven solution can be shared as a pattern, so someone else can reproduce it.
The service stays on hardware you own. A card is the pattern of how you published it: the programs, the images, the ports, the auth mode on each hostname, and which apps share a serving device.
It is a useful way to hand that pattern to someone else, and a natural fit for Edgible, because an app is already a port, an auth mode, and a serving device. The hostname is created when you publish, so the card leaves out your device name, your hostnames, and your organization id. The next person maps each place to a serving device they have, and Edgible publishes the apps. The auth mode stays None, org, or api-key, separate from the program.
A Compose file says how each program runs. A card adds which hostname is open, which one asks for an org login, and which apps have to share a serving device. That pattern is worth sharing when several apps have to coexist and work together to solve one problem.
What you stop doing is rebuilding a known setup from memory. Website on Edgible and n8n on Edgible are each several apps working together, so this series reproduces each one from a card. The website is four apps in two places. n8n is two hostnames on one process, the editor on org and the hooks on None. One app on one port is a single edgible app create existing, which is the whole job.
The cards live in Edgible/cards. card.schema.json is the source of truth for the file. card-to-stack.py writes the stack file, filling in your device name and your organization id. When a card includes tailor.sh, that card's README is how you run it. 1. The website card and 2. The n8n card use the files from that repo.
Each chapter is one job and one smoke test. Do them in order.
Chapters share a shape: a one-line hook under the title, then N.0 Why (what is missing without this chapter, and which machine you run it on), then N.1 The job (what you'll do, how you'll know, what you need, what this is not). Steps after that, a Verify checklist that mirrors Done when, and Next at the end.
