+## 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.

+# 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

+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()

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
