+# Plainpages
+
+A self-hostable foundation for server-rendered web apps — public or gated pages from a
+zero-JS design system, with a config-driven menu and auth/permissions (Ory) baked in.
+Every domain feature is a drop-in plugin folder; the app is stateless, no build step.
+
+**Source, docs & issues: <https://gitea.larvit.se/larvit/plainpages>**
+([GitHub mirror](https://github.com/larvit/plainpages))

+`X.Y.Z` · `X.Y` · `X` · `latest` — each is a release promoted from a CI-gated build.
+Pin the exact `X.Y.Z` you deploy.
+
+## Quick start
+
+This image is the Plainpages web app plus its one-shot bootstrap seeder. It runs
+alongside its Ory sidecars (Kratos, Keto) and Postgres — and it **ships their config**,
+so there is nothing to clone. In an empty directory, save this as `compose.yml`:

+mkdir -p plugins
+docker compose up -d
+```
+
+Open <http://localhost:3000> and sign in as `admin@plainpages.local` / `admin`.
+
+This quick start runs http-on-localhost with dev-throwaway secrets, and omits Hydra (the
+OAuth2 provider — only needed when other apps log in *through* Plainpages). For
+production — https, real secrets (`CSRF_SECRET`, Postgres credentials, a fresh JWT
+signing key), Hydra — see the repo README → Production & deployment.
+
+## Configuration
+
+Every behaviour is an explicit env toggle read at boot — no `NODE_ENV`. The common ones:
+
+| Var | Default | What |
+| --- | --- | --- |
+| `ADMIN_EMAIL` / `ADMIN_PASSWORD` | `admin@plainpages.local` / `admin` | the seeded first admin (bootstrap service) |
+| `APP_URL` | unset | canonical public URL; off-host visitors are redirected to it |
+| `CACHE_TEMPLATES` | `false` | cache compiled templates (`true` in prod) |
+| `CSRF_SECRET` | dev throwaway | signs the CSRF token — set a real one in prod |
+| `KRATOS_*` / `KETO_*` / `HYDRA_*` URLs | compose defaults | the Ory sidecar endpoints |
+| `LOG_FORMAT` / `LOG_LEVEL` | `text` / `info` | `json` for structured prod logs |
+| `OTLP_ENDPOINT` | unset | export logs + traces to an OpenTelemetry Collector |
+| `REQUIRE_SECURE_SECRETS` | `false` | `true` ⇒ refuse to boot on a missing/throwaway `CSRF_SECRET` |
+| `SECURE_COOKIES` | `false` | mark cookies `Secure` (`true` behind https) |
+
+Full list (JWT/JWKS, timeouts, instant revoke): repo README → Configuration.
+
+## Your first plugin
+
+Everything domain-specific is a plugin folder — the compose above mounts `./plugins`
+into the app. Create `plugins/hello/plugin.ts`:
+
+```ts
+import { definePlugin } from "#plugin-api";
+
+export default definePlugin({
+  apiVersion: "1.0.0",
+  nav: [{ href: "/hello", id: "hello", label: "Hello", public: true }],
+  routes: [
+    { method: "GET", path: "/", public: true, handler: () => ({ html: "<h1>Hello from my plugin</h1>" }) },
+  ],
+});
+```
+
+Restart (`docker compose restart web`) and visit <http://localhost:3000/hello>. Views,
+forms, permissions, and the runnable reference plugin: repo README → Building plugins.

 - [x] CI/CD - Sync up to github after every successful merge to main, URL: git@github.com:larvit/plainpages.git - also note the true home top of the README. Force push to github, it should only ever be a mirror of the gitea.larvit.se repository. (`.gitea/workflows/mirror.yml` force-pushes main + tags over HTTPS with a dedicated account's PAT in the `MIRROR_GITHUB_TOKEN` secret; setup documented in README → CI/CD.)
 - [x] CI/CD - Build docker images as part of the requirements to be able to merge to main. Push them with the git commit hash as docker tag. Push to container registry at Gitea. (`ci.yml` builds + pushes `gitea.larvit.se/larvit/plainpages:<commit hash>` after a green gate — with ff-only merges that is the main commit's image; auth via the `DOCKER_REGISTRY_USER` variable + `DOCKER_REGISTRY_TOKEN` secret, retention via an org cleanup rule; documented in README → CI/CD.)
 - [x] CI/CD - Re-tag docker images from git hash to semver when a semver git tag is pushed. (`release.yml` on a `vX.Y.Z` tag pulls the commit-hash image and re-tags it `X.Y.Z`/`X.Y`/`X`/`latest`, failing loud if the gated image is missing; tag pushes also trigger the GitHub mirror; documented in README → CI/CD.)

+- [x] CI/CD - Sync docker images to docker hub after each re-tag to git tags. (`release.yml` pushes the same `X.Y.Z`/`X.Y`/`X`/`latest` tags to `docker.io/larvit/plainpages` after the Gitea re-tag — releases only, no hash tags; auth via the `DOCKERHUB_USER` variable + `DOCKERHUB_TOKEN` secret; documented in README → CI/CD.)
+- [x] Write a short text on how to use this docker image to publish on docker hub and save it to README-dockerhub.md (tagline, tags, clone-free quick start — the image ships the Ory config, extracted via `docker run … tar` + a self-contained compose.yml — env table, first plugin; pasted into the Docker Hub overview by hand — noted in README → CI/CD.)
+- [x] CI/CD - Setup renovate bot. Check how other repos on this Gitea is setup you can get access to, there should be a number of renovate bot activated ones. (`renovate.yml` runs the self-hosted `renovate/renovate` image nightly against `renovate.json` — this repo only, via the shared `renovate@larvit.se` bot + `RENOVATE_TOKEN` secret, mirroring the `pwrpln/core` pattern; standard managers cover npm/Dockerfiles/compose/gitea-action pins, two custom regex managers cover the image tags embedded in workflow `run:` steps, the Ory + Playwright lockstep sets are grouped, every bump stays an exact pin, and each PR automerges once the gate is green; documented in README → CI/CD.)
+- [ ] CI/CD - When renovate updates a dependency - also release a new version of plainpages based on what got updated with Renovate. Major typescript? New apiVersion + new major. A tiny patch to ejs? Only patch release etc.
 - [ ] Add an e2e test for the admin plugin's OAuth2-clients (Hydra) screen. The full-flow e2e suite runs without Hydra (compose.full.yml), so /admin/clients register/detail/delete is only unit-covered (src/http/app.test.ts); wire Hydra into an e2e stack and drive the screen in the browser.
 - [ ] Build and publish docker image as CI/CD.
 - [ ] Add i18n support.
