+### Dynamic DNS Configuration (Automated)
+
+The install script automatically configures Namecheap Dynamic DNS to make the stream accessible at blackportaldetroit.com without requiring a static IP address.
+
+#### What gets installed:
+
+- **ddclient** - Updates your domain's IP address automatically
+- **Configuration file** - Pre-configured for Namecheap at `/etc/ddclient.conf`
+- **Systemd service** - Runs ddclient as a background service
+- **Icecast on port 80** - Eliminates need for router port forwarding
+
+#### Manual steps required after installation:
+
+1. **In Namecheap account**: Enable Dynamic DNS for blackportaldetroit.com
+2. **Add DNS record**: Create an "A + Dynamic DNS" record for "@" (root domain)
+3. **Get password**: Note the Dynamic DNS password from Namecheap
+4. **Update config**: Edit `/etc/ddclient.conf` and replace `REPLACE_WITH_NAMECHEAP_DDNS_PASSWORD`
+5. **Start service**: Run `sudo systemctl start ddclient`
+6. **No router setup needed** - icecast runs directly on port 80
+
+#### Verify Dynamic DNS is working:
+
+```bash
+# Check ddclient status
+sudo systemctl status ddclient
+
+# View ddclient logs
+sudo journalctl -u ddclient -f
+
+# Test DNS resolution
+nslookup blackportaldetroit.com
+```

 # Hardware setup instructions
+
 This readme contains insructions for plugging in the system and turning it on. Full software setup documentation is in the broadcaster-software.md and listener-software.md files.
 
 Make sure to do the following steps in the order they are listed:
 
-
 ## Requirements
-* Modem and internet plan with a static public ip address.
-* Provisioned [broadcaster](broadcaster.md)
-* Provisioned [listener](listener.md)
+
+- Modem and internet plan (no static IP required - uses Dynamic DNS).
+- Provisioned [broadcaster](broadcaster.md) with Dynamic DNS configured
+- Provisioned [listener](listener.md)
 
 ## Steps
 
 ### Turn on broadcaster
+
 1. Plug the usb mic cable into a microphone
 2. Plug the usb mic cable into the top right (blue colored) usb port on the broadcaster (raspberry pi 4b)
-4. Plug the ethernet cable into the broadcaster and the router
-5. Plug the power into the broadcaster (this is how you turn it on)
+3. Plug the ethernet cable into the broadcaster and the router
+4. Plug the power into the broadcaster (this is how you turn it on)
 
+### Networking (Simplified with Dynamic DNS)
 
 ### Networking
+
 6. Log into the router.
 7. Find the ip address of the broadcaster (hostname portal) - usually in the advanced > network > dhcp.
-8. Navigate to the NAT forwarding section of the router admin. 
-9. Set your router to forward all traffic coming in on port "80" to port "8000" at the local ip address of the broadcaster.
-10. Set your domain name to point to the static IP address of your modem.
+8. No port forwarding needed - icecast runs directly on port 80.
+9. The broadcaster will automatically update blackportaldetroit.com with the current public IP address via Dynamic DNS.
 
 ### Turn on listener
+
 1. Turn on the listener (raspberry pi zero). plug it into a monitor and keyboard. when it boots, type sudo raspi-config. navigate to system settings and change the wifi settings so it can access the internet.
-2. Type sudo vim /lib/systemd/system/listener.service and edit the line that says "ExecStart=mplayer -playlist http://" changing the http:// part to the static ip address of the router.
-3. Type esc, w, q, enter
-4. Type sudo systemctl restart listener
-5. mic check
+2. The listener is pre-configured to stream from http://blackportaldetroit.com/portal.m3u - no manual configuration needed.
+3. Type sudo systemctl restart listener
+4. mic check
 
 ### Important notes
+
 * The microphone must always be plugged into the broadcaster before the broadcaster is on
-* The broadcaster must always be on when the listener is turned on. if it is not, then the listener needs to be restarted once the broadcaster is on.
\ No newline at end of file
+* The broadcaster must always be on when the listener is turned on. if it is not, then the listener needs to be restarted once the broadcaster is on.
+* Dynamic DNS automatically keeps blackportaldetroit.com pointed to your current IP address
+* No router port forwarding required - icecast runs directly on port 80
