+## Conversation Layer System
+
+This repository contains the services for the conversation layer, managed by Docker Compose. It includes:
+
+*   **OpenWA:** Handles WhatsApp communication.
+*   **Chat UI:** Provides a user interface for conversations.
+*   **WhatsApp Router:** Connects OpenWA to the Chat UI and an LLM agent.
+
+## Prerequisites
+
+*   Docker (https://www.docker.com/get-started)
+*   Docker Compose (usually included with Docker Desktop)
+
+## Setup and Running
+
+1.  **Clone the repository:**
+    ```bash
+    git clone <your-repo-url>
+    cd <your-repo-directory>
+    ```
+
+2.  **Configure OpenWA:**
+    *   Open the `docker-compose.yml` file.
+    *   **Crucial:** Locate the `openwa` service definition. You may need to replace the placeholder image `image: devlikeapro/open-wa-api:latest` with the specific OpenWA Docker image you intend to use.
+    *   Consult the documentation for your chosen OpenWA image to set necessary environment variables under `services.openwa.environment`. For example, you'll likely need to configure the `WEBHOOK_URL` that OpenWA should call. The `whatsapp-router` service expects this webhook at `http://whatsapp-router:3001/webhook`. So, an example for OpenWA's configuration might be `WEBHOOK_URL=http://whatsapp-router:3001/webhook`.
+    *   Adjust port mappings for `openwa` if your image uses different ports than the defaults provided (API `8080`, Webhook `3000`).
+
+3.  **Configure Service Endpoints (if necessary):**
+    *   **Chat UI (`chat-ui` service):** If the Chat UI needs to know the endpoint of your LLM agent, set the `LLM_AGENT_URL` (or similar) environment variable in `docker-compose.yml` under `services.chat-ui.environment`.
+    *   **WhatsApp Router (`whatsapp-router` service):** This service is pre-configured to look for OpenWA at `http://openwa:8080`. If your LLM agent is called by the router, set its URL via an environment variable like `LLM_AGENT_URL` under `services.whatsapp-router.environment`.
+
+4.  **Build and run the services:**
+    ```bash
+    docker-compose up --build
+    ```
+    *   The `--build` flag ensures images are built if they don't exist or if Dockerfiles/contexts have changed.
+    *   To run in detached mode (in the background), use `docker-compose up -d --build`.
+
+5.  **Accessing Services:**
+    *   **OpenWA API:** Typically `http://localhost:8080` (or the host port you mapped).
+    *   **WhatsApp Router:** `http://localhost:3001` (its webhook is at `http://localhost:3001/webhook`, but this is for OpenWA to call internally).
+    *   **Chat UI:** `http://localhost:3002`.
+
+6.  **Initial OpenWA Setup:**
+    *   After starting, OpenWA will likely require you to scan a QR code with your WhatsApp mobile app to link it. Check the logs of the `openwa` service for the QR code or instructions:
+        ```bash
+        docker-compose logs openwa
+        ```
+    *   Session data for OpenWA is stored in a Docker volume named `openwa_data` to persist the session across restarts.
+
+7.  **Stopping the services:**
+    ```bash
+    docker-compose down
+    ```
+    *   To remove volumes (like `openwa_data`, which will clear the session), use `docker-compose down -v`.
+
+## Project Structure
+
+*   `docker-compose.yml`: Defines and configures all the services.
+*   `chat-ui/`: Contains the Dockerfile and source code for the Chat UI service.
+    *   `Dockerfile`: Instructions to build the Chat UI Docker image.
+    *   `server.js`: Placeholder Node.js/Express application.
+    *   `package.json`: Node.js project manifest.
+*   `whatsapp-router/`: Contains the Dockerfile and source code for the WhatsApp Router service.
+    *   `Dockerfile`: Instructions to build the WhatsApp Router Docker image.
+    *   `router.js`: Placeholder Node.js/Express application with a webhook.
+    *   `package.json`: Node.js project manifest.
+*   `.gitignore`: Specifies intentionally untracked files that Git should ignore.
+*   `README.md`: This file.
