-# Django SaaS example app
+# Feature flags: Django 3 SaaS
 
-A Django 3.0+ SaaS application for testing PostHog wizard integration. This app provides subscription billing, user authentication, and project management features.
+Runs the `wizard feature-flags` e2e against the source tree of
+[`basic-integration/django/django3-saas`](../../../basic-integration/django/django3-saas),
+named by `sourceApp` in `.wizard-ci/source.json`. PostHog is not installed there.
 
-## Running the app
+There is no code here on purpose: a copy of the app would drift from the one it
+was copied from.
 
-### Prerequisites
+Expected wizard outcome, graded by `services/wizard-ci/feature-flag-checks.ts`
+against the keys in `.wizard-ci/feature-flags.json`:
 
-- Python 3.10+
-- SQLite (included with Python, used by default)
-- Stripe account (optional, app runs in demo mode without it)
+- the backend example flag exists in the project, inactive at 0% rollout; the
+  templates hold no scripts, so there is no frontend side and no frontend flag
+- the key appears in exactly one changed file, its constants module, and
+  another changed file imports that module
+- no changed file holds a `wizard-example-*` key outside that list
+- `posthog-feature-flags-report.md` exists
 
-### Installation
-
-1. Create and activate a virtual environment:
-
-```bash
-python -m venv venv
-source venv/bin/activate  # On Windows: venv\Scripts\activate
-```
-
-1. Install dependencies:
-
-```bash
-pip install -r requirements.txt
-```
-
-1. Set up environment variables (create a `.env` file):
-
-```bash
-SECRET_KEY=your-secret-key
-# DATABASE_URL=postgresql://...  # Optional, defaults to SQLite
-STRIPE_PUBLIC_KEY=pk_test_...    # Optional, enables Stripe
-STRIPE_SECRET_KEY=sk_test_...    # Optional, enables Stripe
-STRIPE_WEBHOOK_SECRET=whsec_...  # Optional, for webhooks
-```
-
-> **Note:** By default, the app uses SQLite (`db.sqlite3`) and runs in demo mode without Stripe. No additional setup is required for local development.
-
-1. Initialize the database:
-
-```bash
-python manage.py migrate
-python manage.py seed_plans  # Optional: seed pricing plans
-```
-
-1. Run the development server:
-
-```bash
-python manage.py runserver
-```
-
-The app will be available at `http://127.0.0.1:8000`.

+The flag checks cannot prove this run created the flag: CI never deletes the
+shared key, because parallel legs share it.
