+# Plan 05-03 Summary: Deployment README & Testing
+
+## What Was Built
+
+### Task 1: Deployment README
+- Complete deployment guide at `README.md`
+- Step-by-step installation instructions for Unraid
+- Documents n8n container configuration (Docker socket, curl binary)
+- Documents credential creation (Telegram API, user ID auth)
+- Usage section with all 6 commands
+
+### Task 2: End-to-End Testing
+All commands verified working via Telegram:
+- **Menu**: /start and unknown text show command list
+- **Status**: Lists containers with status indicators
+- **Start/Stop/Restart**: Control containers with confirmation messages
+- **Update**: Pulls image, recreates container, notifies if already up-to-date
+- **Logs**: Configurable line count, HTML-escaped output
+
+## Bug Fixes During Testing
+
+| Issue | Fix | Commit |
+|-------|-----|--------|
+| Show Menu 404 | Switched to native Telegram node | 0b6dfe6 |
+| HTML parse error in menu | Changed `<name>` to `[name]` | 0b6dfe6 |
+| Container matching (jellyplex vs plex) | Prioritize exact matches | 004911e |
+| Update missing acknowledgment | Send "Updating..." immediately | d03e79c |
+| Pull rate limiting | Added error detection for toomanyrequests | d03e79c |
+| Old image not removed | Added image cleanup after update | 0839c44 |
+| Old image removal failed | Fixed data reference through Telegram node | 88830a8 |
+| Pull hanging/memory exhaustion | Pipe output through `tail -c 10000` | 3e3b9ae |
+| Pull downloading all tags | Append `:latest` when tag missing | 74dd8f1 |
+| Logs HTML parse error | Escape `<`, `>`, `&` in log content | 287c722 |
+| Logs line count ignored | Fix property name `lineCount` → `lines` | 808d1af |
+| No message when up-to-date | Add "already up to date" notification | c979a7f |
+
+## Decisions Made
+
+| Decision | Rationale |
+|----------|-----------|
+| Text menu over keyboard | Native Telegram node's replyKeyboard had issues |
+| Hardcoded user ID | n8n IF nodes don't support $credentials references |
+| Exact match priority | Prevents substring collisions (plex/jellyplex) |
+| 10-minute pull timeout | Balance between large images and feedback |
+| Tail last 10KB of pull output | Capture errors without memory exhaustion |
+| Default to :latest tag | Prevents Docker from pulling all tags |
+| HTML escape log content | Logs may contain `<tag>` text |
+
