+# Developer Guide for Notedeck Chrome
+
+This guide covers the technical details of the Notedeck Chrome component, which serves as the container and navigation framework for the Notedeck Nostr browser.

+
+## Key Components
+
+### Chrome
+
+The `Chrome` struct (`src/chrome.rs`) is the main container that:
+- Maintains a list of applications
+- Renders the sidebar
+- Handles application switching
+- Processes UI actions
+
+### NotedeckApp
+
+The `NotedeckApp` enum (`src/app.rs`) represents different applications that can be managed by the Chrome:
+- `Columns` - The main Damus columns interface
+- `Dave` - The Dave application
+- `Other` - Generic container for other implementations of the `App` trait
+
+### Setup
+
+The `setup.rs` file handles initialization of:
+- Font loading
+- Theme setup
+- Window configuration
+- App icons
+
+## Architecture Overview
+
+Notedeck Chrome follows a container-based architecture:
+
+1. The `Chrome` struct maintains a vector of applications
+2. It controls which application is active via an index
+3. The sidebar is rendered with buttons for each application
+4. When an application is selected, it's updated within the container
+
+## Android Support
+
+Android integration relies on:
+- Native Android UI integration via `GameActivity`
+- Custom keyboard height detection for improved mobile UX
+- Configuration via external JSON files
+
+### Android Keyboard Handling
+
+The Android integration includes custom Java code to handle keyboard visibility changes:
+- `KeyboardHeightProvider` - Detects keyboard height changes
+- `KeyboardHeightObserver` - Interface for keyboard events
+- `MainActivity` - Main Android activity with JNI integration
+
+## Styling and Theming
+
+The theme system supports:
+- Light and dark mode
+- OLED-optimized dark mode for mobile
+- Customizable text styles
+- Font loading with multiple typefaces
+
+## Building and Running
+
+### Desktop
+
+```bash
+# Run in debug mode
+cargo run -- --debug
+
+# Run in release mode
+cargo run --release
+```
+
+## Testing
+
+The project includes tests for:
+- Database path configuration
+- Command-line argument parsing
+- Column initialization
+
+Run tests with:
+
+```bash
+cargo test
+```
+
+## Configuration and Data Paths
+
+- Desktop: Uses the platform-specific data location or current directory
+- Android: Uses the Android app's internal storage
+- Custom paths can be specified via command-line arguments
+
+## Advanced Debugging
+
+- Enable the `debug-widget-callstack` feature to debug UI hierarchy
+- Enable the `debug-interactive-widgets` feature to highlight interactive areas
+- Android logging uses `tracing-logcat` for detailed diagnostics
+
+## Code Workflow
+
+1. `notedeck.rs` is the entry point, which initializes `Notedeck`
+2. `setup.rs` configures the application environment
+3. `Chrome` is created and populated with applications
+4. The main UI loop renders the sidebar and active application
+
+## Key Files for Modification
+
+- `chrome.rs` - To modify the sidebar or app container behavior
+- `theme.rs` - To update theming and colors
+- `setup.rs` - To change startup configuration
+- `android.rs` - For Android-specific changes
+
+## Adding a New Application
+
+1. Implement the `notedeck::App` trait for your application
+2. Add a new variant to the `NotedeckApp` enum if needed
+3. Update the `Chrome::topdown_sidebar` method to add a button for your app
+4. Add your app to the `Chrome` instance in `notedeck.rs`

+# Notedeck Chrome
+
+Notedeck Chrome is the UI framework and container for the Notedeck Nostr browser. It manages multiple applications within a single cohesive interface, providing a consistent navigation experience through a persistent sidebar.

+
+The Chrome component provides:
+
+- A consistent, unified sidebar for navigation between applications
+- Theme management (light/dark mode support)
+- Profile picture and account management
+- Settings access
+- Wallet integration
+
+## Features
+
+- **Application Switching**: Switch between Damus columns view and Dave seamlessly
+- **Theme Support**: Toggle between light and dark modes
+- **Profile Management**: Quick access to account settings
+- **Responsive Design**: Compatible with desktop and mobile interfaces
+- **Android Support**: Native support for Android devices
+
+## Development Status
