- Add IPC handlers for zone operations (add_copper_pour, refill_zones)
- Add IPC handlers for board operations (add_board_outline, add_mounting_hole, get_layer_list)
- Add IPC handlers for component operations (rotate_component, get_component_properties)
- Add IPC handlers for net operations (delete_trace, get_nets_list)
- Implement hybrid footprint placement (SWIG library loading + IPC placement)

 ## Overview
 
-The IPC backend is now **fully integrated** as the **default backend** for all MCP tools. When KiCAD is running with IPC enabled, all commands automatically use real-time UI synchronization. Changes made through the MCP tools appear **instantly** in the KiCAD UI without requiring manual reload.
+The IPC backend provides real-time UI synchronization with KiCAD 9.0+ via the official IPC API. When KiCAD is running with IPC enabled, commands can update the KiCAD UI immediately without requiring manual reload.
 
-**SWIG backend is deprecated** and will be removed in a future version when KiCAD removes it (KiCAD 10.0).
+This feature is experimental and under active testing. The server uses a hybrid approach: IPC when available, automatic fallback to SWIG when IPC is not connected.

 ## Known Limitations

-2. **Project creation**: Must be done through KiCAD UI or file system
+2. **Project creation**: Not supported via IPC, uses file system
-3. **Footprint library access**: Limited - best to use library management separately
+3. **Footprint library access**: Uses hybrid approach (SWIG loads from library, IPC places)
-4. **Layer management**: Layers are predefined in KiCAD
+4. **Delete trace**: Falls back to SWIG (IPC API doesn't support direct deletion)
+5. **Some operations may not work as expected**: This is experimental code

+## IPC Backend (Under Development)
+
+We are currently implementing and testing the KiCAD 9.0 IPC API for real-time UI synchronization. This is experimental and may not work perfectly in all scenarios.
+
+### IPC-Capable Commands (21 total)
+
+The following commands have IPC handlers implemented:
+

+| `route_trace` | `_ipc_route_trace` | Implemented |

+| `get_component_properties` | `_ipc_get_component_properties` | Implemented |
+| `save_project` | `_ipc_save_project` | Implemented |
+
+### How IPC Works
+
+When KiCAD is running with IPC enabled:
+1. Commands check if IPC is connected
+2. If connected, use IPC handler for real-time UI updates
+3. If not connected, fall back to SWIG API
+
+**To enable IPC:**
+1. KiCAD 9.0+ must be running
+2. Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
+3. Have a board open in the PCB editor
+
+### Known Limitations
+
+- KiCAD must be running for IPC to work
+- Some commands may not work as expected (still testing)
+- Footprint loading uses hybrid approach (SWIG for library, IPC for placement)
+- Delete trace falls back to SWIG (IPC API limitation)

-### Week 2 Goals (NEARLY COMPLETE)
-
-**Must Have:**

+- **Status:** Stable and functional
 - **Pros:** No KiCAD process required, works offline, reliable
 - **Cons:** Requires manual file reload for UI updates, no zone filling

-### IPC Backend (Week 3) **NEXT PRIORITY**
+### IPC Backend (Real-time)
-- **Status:** Planned, not yet implemented
+- **Status:** Under active development and testing
-- **Pros:** Real-time UI updates (<100ms), no file I/O, zone filling works
+- **Pros:** Real-time UI updates, no file I/O for many operations, zone filling works
-- **Cons:** Requires KiCAD running, more complex
+- **Cons:** Requires KiCAD running, experimental
-- **Future:** Primary backend for interactive use
+- **Use Case:** Interactive design sessions, paired programming with AI
+
+### Hybrid Approach
+The server automatically selects the best backend:
+- IPC when KiCAD is running with IPC enabled
+- SWIG fallback when IPC is unavailable
