+# 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))
+
+## Tags
+
+`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 Ory Kratos, Keto, Hydra and Postgres, all wired by the repo's compose files:
+
+```bash
+git clone https://gitea.larvit.se/larvit/plainpages.git
+cd plainpages
+docker compose up -d
+```
+
+Open <http://localhost:3000> and sign in as `admin@plainpages.local` / `admin`.
+(The dev stack builds the image locally and live-reloads.)
+
+To deploy this published image instead of building, add an override and run the
+production stack:
+
+```yaml
+# compose.image.yml
+services:
+  bootstrap:
+    image: larvit/plainpages:0.0.2
+    pull_policy: missing
+  web:
+    image: larvit/plainpages:0.0.2
+    pull_policy: missing
+```
+
+```bash
+CSRF_SECRET=<long random> docker compose -f compose.yml -f compose.image.yml up -d
+```
+
+Production expects https and real secrets (`CSRF_SECRET`, `POSTGRES_USER`/`PASSWORD`,
+a fresh JWT signing key) — 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. 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</h1>" }) },
+  ],
+});
+```
+
+Restart (`docker compose restart web`) and visit <http://localhost:3000/hello>. Views,
+forms, permissions, and the runnable reference plugin: repo README → Building plugins.

+- [ ] 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.
 - [ ] 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.
