-### Web Visualization (Optional)
+### Multi-User System
 
-TrulyMEM provides a Web star-map visualization interface for browsing the knowledge graph in real-time:
+TrulyMEM supports isolated multi-user environments. Each user has their own config and database:
+
+```
+~/.trulymem/
+├── trulymem.db          # Global user database
+├── .migrated            # Migration flag
+├── admin/
+│   ├── config.json      # Admin config
+│   └── admin_graph.db   # Admin knowledge graph
+└── user2/
+    ├── config.json      # user2 config
+    └── user2_graph.db   # user2 knowledge graph
+```
+
+- **First user becomes admin automatically**
+- Admins can add/delete users on the Web settings page
+- Regular users cannot see the user management section
+
+### Web Visualization Interface
+
+From TUI, admin users can enable Web service via the right-side panel checkbox, or start manually:
 
 ```bash

+## Building
+
+TrulyMEM supports PyInstaller packaging into single-file executables:
+
+```bash
+# Linux
+bash build/build_linux.sh
+
+# macOS
+bash build/build_macos.sh
+
+# Windows
+build\build_windows.bat
+
+# AppImage (Linux universal)
+bash build/build_appimage.sh
+```
+
+Build outputs in `dist/`:
+
+| File | Purpose |
+|------|---------|
+| `TrulyMEM` | TUI main program (can spawn Web subprocess) |
+| `trulymem-web` | Web service standalone binary (auto-detected by TUI) |
+
+### Web binary priority (within TUI)
+1. `trulymem-web` in same directory (packaged)
+2. `sys._MEIPASS/web_api.py` (PyInstaller data fallback)
+3. `python3 web_api.py` (development fallback)
