-## 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 the admin dashboard at `http://localhost:8000/` and login with your `ADMIN_PASSWORD` to withdraw your balance as a Cashu token.
+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.

-# 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

+2. **HTTPS Only**: Always access via HTTPS
+3. **Regular Monitoring**: Check logs frequently
+4. **Limited Access**: Restrict dashboard access

-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()
