+# Version 2 Partition Table
+
+This version introduces significant improvements over v1 by adding an `assets` partition to support network-loadable content.
+
+## Key Changes from v1
+
+### Added Assets Partition
+The v2 partition table includes a new `assets` partition that stores:
+- **Wake word models**: Customizable wake word models that can be loaded from the network
+- **Theme files**: Complete theming system including:
+  - Fonts
+  - Audio effects
+  - Background images
+  - Custom emoji packs
+
+### Partition Layout Comparison
+
+#### v1 Layout (16MB)
+- `nvs`: 16KB (non-volatile storage)
+- `otadata`: 8KB (OTA data)
+- `phy_init`: 4KB (PHY initialization data)
+- `model`: 960KB (model storage)
+- `ota_0`: 6MB (application partition 0)
+- `ota_1`: 6MB (application partition 1)
+
+#### v2 Layout (16MB)
+- `nvs`: 16KB (non-volatile storage)
+- `otadata`: 8KB (OTA data)
+- `phy_init`: 4KB (PHY initialization data)
+- `model`: 960KB (model storage)
+- `ota_0`: 4MB (application partition 0)
+- `ota_1`: 4MB (application partition 1)
+- `assets`: 7MB (network-loadable assets)
+
+### Benefits
+
+1. **Dynamic Content**: Users can download and update wake word models and themes without reflashing
+2. **Reduced App Size**: Application partitions are smaller, allowing more space for assets
+3. **Customization**: Support for custom themes and wake words enhances user experience
+4. **Network Flexibility**: Assets can be updated independently of the main application
+
+### Available Configurations
+
+- `8m.csv`: For 8MB flash devices
+- `16m.csv`: For 16MB flash devices (standard)
+- `16m_c3.csv`: For 16MB flash devices with ESP32-C3 optimization
