+## Admin UI
+
+Routstr includes a modern Next.js admin dashboard that's served directly from the Python backend as static files - no separate Node.js server required.
+
+### Building the UI
+
+```bash
+make ui-build
+```
+
+This compiles the Next.js application into static HTML, CSS, and JavaScript files in `ui/out/`.
+
+### Accessing the Dashboard
+
+Once built, the UI is automatically served by the FastAPI backend:
+
+- **Dashboard**: `http://localhost:8000/`
+- **Login**: `http://localhost:8000/login`
+- **Models Management**: `http://localhost:8000/model`
+- **Providers Management**: `http://localhost:8000/providers`
+- **Settings**: `http://localhost:8000/settings`
+
+The dashboard provides:
+
+- Real-time wallet balance monitoring
+- Model pricing configuration
+- Upstream provider management
+- Transaction history
+- System settings
+
+**Authentication**: Use the `ADMIN_PASSWORD` environment variable to access the dashboard.
+
 ## Withdrawing Balance
 
-Go to `https://<your.routstr.proxy>/admin/` (NOTE: be sure to add the '/' at the end), enter the `ADMIN_PASSWORD` you set above and withdraw your balance as a Cashu token.
+Go to the admin dashboard at `http://localhost:8000/` and login with your `ADMIN_PASSWORD` to withdraw your balance as a Cashu token.

+Routstr Core is configured via a single settings row in the database. Environment variables are only used on first run to seed that row (with a few computed defaults like `ONION_URL`).

+# UI Configuration
+
+This guide explains how to configure the Routstr UI for different environments.
+
+## Environment Variables
+
+The UI uses Next.js environment variables to configure API endpoints and authentication.
+
+### Centralized Configuration
+
+This project uses a centralized configuration approach with a single `.env` file in the project root. This file contains both backend and frontend configuration variables.
+
+Create or update your `.env` file in the project root:
+
+```bash
+# .env (in project root)
+
+# UI Configuration (NEXT_PUBLIC_ variables are exposed to the browser)
+NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
+```
+
+### Development vs Production
+
+The same `.env` file is used for both development and production. Simply change the values:
+
+**Development:**
+
+```bash
+NEXT_PUBLIC_API_URL=http://127.0.0.1:8000
+```
+
+**Production:**
+
+```bash
+NEXT_PUBLIC_API_URL=https://api.yourroutstr.com
+```
+
+## Building the UI
+
+The build process automatically reads configuration from the root `.env` file:
+
+```bash
+# From the project root
+make ui-build
+# or
+./scripts/build-ui.sh
+```
+
+The build script will automatically:
+
+- Load `NEXT_PUBLIC_*` variables from the root `.env` file
+- Use them during the Next.js build process
+- Display warnings if the `.env` file is missing

 # Admin Dashboard
 
-The Routstr admin dashboard provides a web interface for managing your node, viewing balances, and handling withdrawals.
+The Routstr admin dashboard is a modern web interface for managing your node, monitoring wallet balances, configuring AI models and providers, and handling Bitcoin Lightning payments through Cashu eCash.
 
 ## Accessing the Dashboard
 
-### URL Format
-
-The admin dashboard is available at:
-
-```
-https://api.routstr.com/admin/
-```
-
-> **Important**: Always include the trailing slash (`/`) in the URL.
-
 ### Authentication
 
-The dashboard is protected by a password set in the `ADMIN_PASSWORD` environment variable.
+The dashboard is protected by password authentication:
 
-1. Navigate to `/admin/`
+1. Navigate to `/admin/` in your browser
 2. Enter the admin password
-3. Click "Login"
+3. Optional: Configure custom base URL if not pre-configured
+4. Click "Login"
 
-The password is stored as a secure cookie for the session.
+The interface supports both environment-configured URLs and manual URL entry for deployment flexibility.
 
 ## Dashboard Overview
 
-### Main Interface
+The main dashboard consists of four primary sections accessible through a collapsible sidebar:
 
-The dashboard displays:
+- **Dashboard** - Wallet balance monitoring and fund management
+- **Models** - AI model management and testing
+- **Providers** - Upstream provider configuration
+- **Settings** - Node configuration and admin preferences
 
-- **Node Information**
-  - Node name and description
-  - Version number
-  - Public URLs (HTTP and Onion)
-  - Supported Cashu mints
+### Navigation
 
-- **Statistics**
-  - Total API keys
-  - Active keys
-  - Total balance across all keys
-  - Recent activity
+## Dashboard Page
 
-- **API Key List**
-  - All keys with balances
-  - Usage statistics

+CRITICAL LOG MESSAGES FOR USAGE STATISTICS:
+===========================================
+The following log messages are parsed by the usage tracking system (routstr/core/admin.py).
+DO NOT modify or remove these messages without updating the usage tracking logic:
+
+1. "Received proxy request" (INFO) - routstr/proxy.py
+   - Used to count total incoming requests
+   - Includes model information in context
+
+    2. "Payment adjustment completed for streaming" (INFO) - routstr/upstream/base.py
+       "Payment adjustment completed for non-streaming" (INFO) - routstr/upstream/base.py
+   - Used to track successful completions and revenue
+   - The 'cost_data.total_msats' field is extracted for revenue calculation
+   - Must include 'cost_data' in extra dict
+
+3. "Payment processed successfully" (INFO) - routstr/auth.py
+   - Used to count successful payment processing events
+   - Tracks payment-related metrics
+
+4. "Upstream request failed, revert payment" (WARNING) - routstr/proxy.py
+   - Used to track failed requests and refunds
+   - The 'max_cost_for_model' field is extracted for refund calculation
+   - Must include 'max_cost_for_model' in extra dict
+
+5. Any ERROR level logs with "upstream" in the message
+   - Used to count upstream provider errors
+   - Helps identify service reliability issues
+
+If you need to modify these messages, ensure you also update the parsing logic in:
+- routstr/core/admin.py:_aggregate_metrics_by_time()
+- routstr/core/admin.py:_get_summary_stats()
+- routstr/core/admin.py:get_revenue_by_model()
