 ## Project Overview
 
-FlashForgeWebUI is a standalone web-based interface for controlling and monitoring FlashForge 3D printers. It was ported from the FlashForgeUI-Electron project (located at `C:\Users\Cope\Documents\GitHub\FlashForgeUI-Electron`) to create a lightweight deployment option for low-spec devices like Raspberry Pi, without Electron dependencies.

-**Current Status**: Initial porting is complete but not fully tested. Some bugs are expected.
+**Current Status**: Production-ready. Core functionality tested and working including multi-printer support, Spoolman integration, and cross-platform binary distribution.

 ## Testing Notes
 
-Initial porting is complete but **not fully tested**. Known areas to test:
+Core functionality has been tested and verified:
 - Multi-printer context switching
-- Camera proxy stability under load
-- RTSP streaming for supported printers
 - Spoolman integration (filament tracking)
-- Print state monitoring and notifications
-- Temperature anomaly detection
-- Different printer model backends (AD5X, 5M, 5M Pro, legacy)
+- Platform-specific binary builds (Linux ARM, Linux x64, Windows, macOS)
 - WebUI authentication
-- Platform-specific builds (Linux ARM, Windows, macOS)
+- Static file serving in packaged binaries
+
+Areas for continued testing:
+- Camera proxy stability under extended load
+- RTSP streaming for all supported printers
+- Temperature anomaly detection edge cases

+
+Or if accessing from another device on your network:
+
+```
+http://<server-ip>:3000
+```
+
+**Default Login:** The default password is `changeme`. You should change this in `data/config.json` or via the `--webui-password` flag.

+  <h2>Troubleshooting</h2>
+</div>
+
+**"Cannot GET /" or blank page when accessing WebUI:**
+- If running from source: Make sure you ran `npm run build` before `npm start`
+- If using a pre-1.0.2 binary: Update to version 1.0.2 or later (fixes static file serving bug)
+
+**"Permission denied" when running binary:**
+```bash
+chmod +x flashforge-webui-linux-*
+```
+
+**Port already in use:**
+- Change the port in `data/config.json` or use `--webui-port=3001`
+
+**Cannot connect to printer:**
+- Ensure your printer is on the same network as the device running WebUI
+- Check that the printer's IP address is correct
+- For legacy printers, ensure TCP port 8899 is accessible
+
+**Selecting the correct binary for your platform:**
+- Windows: `flashforge-webui-win-x64.exe`
+- macOS Intel: `flashforge-webui-macos-x64`
+- macOS Apple Silicon: `flashforge-webui-macos-arm64`
+- Linux x64: `flashforge-webui-linux-x64`
+- Raspberry Pi (64-bit OS): `flashforge-webui-linux-arm64`
+- Raspberry Pi (32-bit OS): `flashforge-webui-linux-armv7`
+- Check your architecture with `uname -m` (x86_64 = x64, aarch64 = ARM64, armv7l = ARMv7)
