+## Initial Setup (.env file)
+
+Before running your node, you should create a `.env` file in the project root. This file is used to bootstrap the initial configuration and store sensitive secrets.
+
+### Example .env
+
+```bash
+ADMIN_PASSWORD=your-secure-password
+
+# Node Identity
+NAME="My AI Node"
+DESCRIPTION="Fast access to models"
+
+# Lightning Payouts
+RECEIVE_LN_ADDRESS=yourname@wallet.com
+```
+
+### Setting the UI Password
+
+There are two ways to set or change your Admin Dashboard password:
+
+1.  **Via Environment Variable**: Set `ADMIN_PASSWORD` in your `.env` file before starting the container. This will be the password used for the first login.
+2.  **Via Dashboard**: Once logged in, go to **Settings** → **Security** to update your password. Dashboard settings override the `.env` file once saved.

+### Advanced Setup (Separated UI & Node)
+Use the included `compose.yml` for a more flexible setup that separates the UI build process from the node execution. This is useful for development or when you want to manage Tor as a separate service.
 
 ```bash
 docker compose up -d
 ```
 
-Then configure everything via the [Admin Dashboard](http://localhost:8000/admin/).
+This will:
+1.  **Build the UI**: Compiles the frontend and copies it to a shared volume.
+2.  **Start Routstr**: Runs the Python node, mounting the built UI.
+3.  **Start Tor**: Provides anonymous access via a `.onion` address.

-"""Unit tests for model row payload conversion.
-
-This module tests that _model_to_row_payload correctly serializes model data
-for database storage. Pricing is stored as-is without fee application.
-Fees are now applied per-provider when reading from the database.
-
-Key behaviors tested:
-1. Pricing is stored as-is without fee application
-2. All model fields are correctly serialized to JSON
-3. Optional fields are handled correctly (None values)
-4. Pricing structure is preserved
-5. Original model objects are not mutated
