Correct README wording for role-based access and VIP edition

The 'user' role description implied OSS users can get per-account
create rights - that's a VIP-only feature. Also replaced the VIP
edition blurb with clearer wording about what the subscription
actually unlocks.

-**PHP Dynamic Qr code** is a script that allows the generation and saving of dynamic and static QR codes. It has a clean, responsive, and user-friendly design. It is based on [AdminLte](https://adminlte.io/), the "Best open source admin dashboard & control panel theme. Built on top of Bootstrap" and [Core PHP Admin Panel](https://github.com/chetans9/core-php-admin-panel), a simple Admin Panel written in core PHP that contains an implementation of general features you might need in your website admin panel like: record management (CRUD), secure authentication, pagination, filters.

+- **Try it free:** [qr.ensembia.com](https://qr.ensembia.com) - fully functional OSS test
+  instance. Self-service signup isn't live yet, so log in with the temporary shared demo
+  account `admin` / `admin` in the meantime.
+- **Commercial VIP edition:** the ability to give sub-users the ability to create
+  QR codes as well, from their own (sub)account. If you have a bigger organisation,
+  having more users being able to create new QR codes delegates your workload. To
+  fund our open-source project, a small fee (€49/year subscription per organisation
+  ("tenant")) is requested for this. [www.qrforge.eu](https://www.qrforge.eu).
+- **Self-host it yourself:** this repository, MIT-licensed.

-## Setup with docker compose
-1. download docker-compose.yml file
-2. Start docker stack
-```bash
-docker compose build --no-cache && docker compose up -d
-```
-3. Open your browser at http://localhost:80 and login with (username: superadmin, password: superadmin)
+# Setup with Docker Compose
+
+1. Clone this repository.
+2. Copy `.env.example` to `.env` and set a real `DATABASE_PASSWORD` /
+   `MYSQL_ROOT_PASSWORD`.
+3. Start the stack:
+   ```bash
+   docker compose up -d --build
+   ```
+4. Open `http://localhost` and log in with `superadmin` / `superadmin`. You'll
+   be required to set a new password on first login.
+
+For a production deployment behind a reverse proxy, use
+`docker-compose.prod.yml` (Nginx + PHP-FPM) instead of the dev stack.
