+# VSCode Deepnote Extension Architecture
+
+This extension adds support for Deepnote notebooks in Visual Studio Code. Deepnote is a collaborative data science notebook platform, and this extension allows users to open, edit, and manage Deepnote project files (`.deepnote` files) directly within VS Code.
+
+## Key Components
+
+### 1. Notebook Serializer (`deepnoteSerializer.ts`)
+
+The core component responsible for converting between Deepnote's YAML format and VS Code's notebook format.
+
+**Responsibilities:**
+
+- **Deserialization**: Converts Deepnote YAML files into VS Code NotebookData format
+- **Serialization**: Converts VS Code notebook changes back to Deepnote YAML format
+- **State Management**: Maintains original project data for accurate serialization
+
+**Key Methods:**
+
+- `deserializeNotebook()`: Parses YAML, converts blocks to cells
+- `serializeNotebook()`: Converts cells back to blocks, updates YAML
+- `findCurrentNotebookId()`: Determines which notebook to deserialize using manager state
+
+### 2. Data Converter (`deepnoteDataConverter.ts`)
+
+Handles the transformation between Deepnote blocks and VS Code notebook cells.
+
+**Responsibilities:**
+
+- Convert Deepnote blocks (code, markdown, SQL, etc.) to VS Code cells
+- Convert VS Code cells back to Deepnote blocks
+- Preserve block metadata and outputs during conversion
+
+**Supported Block Types:**
+
+- Code blocks (Python, R, JavaScript, etc.)
+- Markdown blocks
+
+### 3. Notebook Manager (`deepnoteNotebookManager.ts`)
+
+Manages the state of Deepnote projects and notebook selections.
+
+**Responsibilities:**
+
+- Store original project data for serialization
+- Track which notebook is selected for each project
+- Maintain project-to-notebook mapping using project IDs
+
+**Key Features:**
+
+- In-memory caching of project data
+- Project-ID based notebook selection tracking
+- Support for multiple notebooks per project
+
+**Key Methods:**
+
+- `getTheSelectedNotebookForAProject()`: Retrieves selected notebook ID for a project
+- `selectNotebookForProject()`: Associates a notebook ID with a project ID
+- `storeOriginalProject()`: Caches project data and sets current notebook
+
+### 4. Explorer View (`deepnoteExplorerView.ts`)
+
+Provides the sidebar UI for browsing and opening Deepnote notebooks.
+
+**Responsibilities:**
+
+- Create and manage the tree view in VS Code's sidebar
+- Handle user interactions (clicking on notebooks/files)
+- Register commands for notebook operations
+
+**Commands:**
+
+- `deepnote.refreshExplorer`: Refresh the file tree
+- `deepnote.openNotebook`: Open a specific notebook
+- `deepnote.openFile`: Open the raw .deepnote file
+- `deepnote.revealInExplorer`: Show active notebook info
+
+### 5. Tree Data Provider (`deepnoteTreeDataProvider.ts`)
+
+Implements VS Code's TreeDataProvider interface for the sidebar view.
+
+**Responsibilities:**
+
+- Scan workspace for `.deepnote` files
+- Parse project files to extract notebook information
+- Provide tree structure for the explorer view
+- Watch for file system changes
+
+**Features:**
+
+- Automatic workspace scanning
+- File system watching for real-time updates
+- Caching for performance optimization
+
+### 6. Activation Service (`deepnoteActivationService.ts`)
+
+Entry point for the Deepnote functionality within the extension.
+
+**Responsibilities:**
+
+- Register the notebook serializer with VS Code
+- Initialize the explorer view
+- Set up extension lifecycle
+
+## Data Flow
+
+### Opening a Notebook
+
+1. **User Action**: User clicks on a notebook in the sidebar
+2. **Explorer View**: Handles the click, stores notebook selection using project ID
+3. **Notebook Manager**: Associates the notebook ID with the project ID
+4. **VS Code**: Opens the document using the base file URI and calls `deserializeNotebook()`
+5. **Serializer**:
+ - Uses `findCurrentNotebookId()` to determine which notebook to load
+ - Reads the YAML file and finds the selected notebook
+ - Converts blocks to cells using the Data Converter
+6. **Display**: VS Code displays the notebook in the editor
+
+### Saving Changes
+
+1. **User Action**: User makes changes and saves (Ctrl+S)
+2. **VS Code**: Calls the serializer's `serializeNotebook()` method
+3. **Serializer**:
+ - Retrieves original project data from Notebook Manager
+ - Converts cells back to blocks using the Data Converter
+ - Updates the YAML structure
+ - Writes back to file
+4. **File System**: Updates the `.deepnote` file
+
+## File Format
+
+### Deepnote YAML Structure
+
+```yaml
+version: 1.0
+metadata:
+ modifiedAt: '2024-01-01T00:00:00Z'
+project:
+ id: 'project-uuid'
+ name: 'Project Name'
+ notebooks:
+ - id: 'notebook-uuid'
+ name: 'Notebook Name'
+ blocks:
+ - id: 'block-uuid'
+ type: 'code'
+ source: "print('Hello')"
+ outputs: []
+```
+
+### VS Code Notebook Format
+
+```typescript
+interface NotebookData {
+ cells: NotebookCellData[];
+ metadata: {
+ deepnoteProjectId: string;
+ deepnoteProjectName: string;
+ deepnoteNotebookId: string;
+ deepnoteNotebookName: string;
+ deepnoteVersion: string;
+ };
+}
+```
+
+## Multi-Notebook Support
+
+The extension supports opening multiple notebooks from the same `.deepnote` file:
+
+1. **Project-Based Selection**: The Notebook Manager tracks which notebook is selected for each project
+2. **State Management**: When opening a notebook, the manager stores the project-to-notebook mapping
+3. **Fallback Detection**: The serializer can detect the current notebook from VS Code's active document context
+
+## Technical Decisions
+
+### Why YAML?
+
+Deepnote uses YAML for its file format, which provides:
+
+- Human-readable structure
+- Support for complex nested data
+- Easy to read Git diffs
+
+### Why Project-ID Based Selection?
+
+- Simpler than URI-based tracking - uses straightforward project ID mapping
+- The VS Code NotebookSerializer interface doesn't provide URI context during deserialization
+- Allows for consistent notebook selection regardless of how the document is opened
+- Manager-based approach centralizes state management and reduces complexity
