+# MediaCMS 7.3 - Quick Start
+
+## Minimal Deployment (No Code Required!)
+
+MediaCMS 7.3 can be deployed with **just 2 files**:
+
+1. `docker-compose.yaml`
+2. `custom/` directory (optional)
+
+**No git repo, no code checkout needed!** Everything runs from Docker images.
+
+---
+
+## Fresh Installation
+
+### 1. Create deployment directory
+
+```bash
+mkdir mediacms && cd mediacms
+```
+
+### 2. Download docker-compose.yaml
+
+```bash
+wget https://raw.githubusercontent.com/mediacms-io/mediacms/v7.3/docker-compose.yaml
+```
+
+Or with curl:
+```bash
+curl -O https://raw.githubusercontent.com/mediacms-io/mediacms/v7.3/docker-compose.yaml
+```
+
+### 3. Start MediaCMS
+
+```bash
+docker compose up -d
+```
+
+### 4. Access your site
+
+- **Frontend**: http://localhost
+- **Admin**: http://localhost/admin
+  - Username: `admin`
+  - Password: Check logs for auto-generated password:
+    ```bash
+    docker compose logs migrations | grep "password:"
+    ```
+
+**That's it!** 🎉
+
+---
+
+## Optional: Customization
+
+### Add Custom Settings
+
+```bash
+# 1. Create custom directory
+mkdir -p custom/static/{images,css}
+
+# 2. Download example template
+wget -O custom/local_settings.py.example \
+  https://raw.githubusercontent.com/mediacms-io/mediacms/v7.3/custom/local_settings.py.example
+
+# 3. Copy and edit
+cp custom/local_settings.py.example custom/local_settings.py
+nano custom/local_settings.py
+```
+
+Example customizations:
+```python
+# custom/local_settings.py
+DEBUG = False
+ALLOWED_HOSTS = ['media.example.com']
+PORTAL_NAME = "My Media Portal"
+```
+
+### Add Custom Logo
+
+```bash
+# 1. Copy your logo
+cp ~/my-logo.png custom/static/images/logo_dark.png
+
+# 2. Reference in settings
+cat >> custom/local_settings.py <<EOF
+PORTAL_LOGO_DARK_PNG = "/custom/static/images/logo_dark.png"
+EOF
+
+# 3. Restart (no rebuild needed!)
+docker compose restart web
+```
+
+### Add Custom CSS
+
+```bash
+# 1. Create CSS file
+cat > custom/static/css/custom.css <<EOF
+body {
+    font-family: 'Arial', sans-serif;
+}
+EOF
+
+# 2. Reference in settings
+cat >> custom/local_settings.py <<EOF
+EXTRA_CSS_PATHS = ["/custom/static/css/custom.css"]
+EOF
+
+# 3. Restart (no rebuild needed!)
+docker compose restart web
+```
+
+**Note**: Both settings AND static files only need restart - nginx serves custom/ files directly!
+
+---
+
+## HTTPS with Let's Encrypt
+
+### 1. Download cert overlay
+
+```bash
+wget https://raw.githubusercontent.com/mediacms-io/mediacms/v7.3/docker-compose-cert.yaml
+```
+
+### 2. Edit domains
+
+```bash
+nano docker-compose-cert.yaml
+```
+
+Change these lines:
+```yaml
+VIRTUAL_HOST: 'media.example.com'        # Your domain
+LETSENCRYPT_HOST: 'media.example.com'    # Your domain
+LETSENCRYPT_EMAIL: 'admin@example.com'   # Your email
+```
+
+### 3. Start with SSL
+
+```bash
+docker compose -f docker-compose.yaml -f docker-compose-cert.yaml up -d
+```
+
+**SSL certificates are issued automatically!**
+

+
+## File Structure

+
+## Troubleshooting
+
+### Can't access the site?
+
+Check services are running:
+```bash
+docker compose ps
+```
+
+All services should be "Up" or "Exited (0)" for migrations.
+
+### Forgot admin password?
+
+Check logs:
+```bash
+docker compose logs migrations | grep "password:"
+```
+
+Or create new admin:
+```bash
+docker compose exec web python manage.py createsuperuser
+```
+
+### Videos not encoding?
+
+Check celery workers:
+```bash
+docker compose logs celery_long
+docker compose logs celery_short
+```
+
+### Port 80 already in use?
+
+Edit docker-compose.yaml to use different port:
+```yaml
+nginx:
+  ports:
+    - "8080:80"  # Use port 8080 instead
+```
+
+Then access at http://localhost:8080
