-## 📖 How to use
+## 👥 Configuration & Profiles
 
-Once installed, the integration provides a new service (action) that you can use in any automation.
+Add your WhatsApp accounts via the Home Assistant UI:
+1. Go to **Settings** -> **Devices & Services**.
+2. Click **Add Integration** and search for **WhatsApp Bridge**.
+3. Follow the setup to add an **Account Name** (e.g., "Work") and your **Phone Number**.
+4. **Repeat** this process for as many accounts as you need.
 
-### Send a Message via YAML
-You can call the service directly in your automations:
+### Resulting Entities
+The integration automatically creates sensors for your UI:
+* `sensor.whatsapp_account_name`: An entity for each individual account.
+* `sensor.whatsapp_broadcast_all`: A global entity to message all accounts at once.
 
+---
+
+## 🛠 Usage
+
+### Action: `send_message`
+This integration registers a service/action to send messages.
+
+**Fields:**
+* **Recipient:** Select an account from the dropdown, choose the "Broadcast" entity, or manually type a phone number.
+* **Message:** The text content you wish to send.
+
+#### YAML Example:
 ```yaml
 action: whatsapp_bridge_integration.send_message
 data:
-  number: "491701234567"
-  message: "The washing machine is finished! 🧺"
+  recipient: "sensor.whatsapp_rene"
+  message: "The garage door is still open!"
 ```
 
-### Use in Node-RED
-Add a Call Service (or Action) node.
-
-Domain: whatsapp_bridge_integration
-
-Service: send_message
-
-Data:
-
-```JSON
-{
-  "number": "491701234567",
-  "message": "{{payload}}"
-}
-```
-
-## 👥 Multi-Account Support (Coming Soon)
-We are currently working on a UI-based configuration flow so you can save "Account Aliases" (like "Dad", "Work", "Security") and select them from a dropdown menu without typing the phone number every time.
-
-##⚠️ Important Notes
+## ⚠️ Important Notes
 Phone Numbers: Always use the international format without + or 00 (e.g., 49... for Germany).
 
 Local Network: The integration communicates locally with the Add-on on port 3000.

+
+## 🤖 Node-RED Integration
+The integration is fully compatible with Node-RED. Since it uses native entities, you can use the standard *Action (Call Service)* node.
+
+### Example: Smart Window Warning
+Notify yourself if a window or door has been left open for 15 minutes.
+
+ 1. *Trigger*: Use a `State Trigger` or `Device` node.
+
+ 2. *Logic (Change Node)*: Use JSONata to create a dynamic message:
+
+  - *Set*: msg.payload
+
+  - *Value (JSONata)*: `payload.to_state.attributes.friendly_name & " has been open for 15 minutes!"`
+
+ 3. WhatsApp Node (Action Node):
+
+  - *Action*: `whatsapp_bridge_integration.send_message`
+
+  - *Data (JSON)*:
+
+```JSON
+{
+   "recipient": "sensor.whatsapp_broadcast_all",
+   "message": "{{payload}}"
+}
+```
+
+### Manual Tool Calling
+To send a message to a number not saved as a profile, simply pass the raw phone number to the recipient field in your Node-RED JSON:
+
+```JSON
+{
+  "recipient": "491701234567",
+  "message": "Direct alert to external number."
+}
+```
+
+---
+
+# ✨ Features
+ - *Dynamic UI*: Accounts are automatically added to the recipient dropdown.
+
+ - *One-Click Broadcast*: Special entity to reach all configured profiles instantly.
+
+ - *Manual Fallback*: Clean UI remains flexible; type any number to bypass profiles.
+
+ - *Developer Friendly*: Designed for easy integration with Node-RED and HA Automations.
