 ## Main Components
 
-- **Scanner/Indexer**: Discovers documentation files in the workspace, caches metadata, and watches for changes.
-- **TreeDataProvider**: Renders the documentation tree in the sidebar, applying ordering and title normalization.
-- **Preview/Open Controller**: Handles file opening (preview/editor) and user interactions.
-- **Settings Manager**: Reads and applies extension settings.
-- **Sync Module**: Keeps the tree in sync with the active editor.
-- **Utilities**: Helpers for title normalization and file type detection.
+- **[Scanner](../../src/scanner/workspaceScanner.ts)**: Discovers documentation files using `workspace.findFiles`, respects `.gitignore` and exclude patterns, filters hidden files, and returns URIs.
+- **[Tree Provider](../../src/tree/treeProvider.ts)**: Implements VS Code's `TreeDataProvider` interface, builds hierarchical tree structure, applies ordering rules, manages node mapping for sync.
+- **[Tree Builder](../../src/tree/buildTree.ts)**: Constructs hierarchical tree from flat file list, calculates common base path, sorts nodes, handles folder/file relationships.
+- **[Preview Controller](../../src/controllers/previewController.ts)**: Handles file opening with double-click detection (500ms threshold), manages preview vs editor modes, respects `openWith` configuration.
+- **[Configuration Utilities](../../src/utils/configUtils.ts)**: Provides typed access to extension settings with default values.
+- **[Text Utilities](../../src/utils/textUtils.ts)**: Normalizes file names to human-readable titles, preserves acronym casing, handles special cases (README).
+- **[File Utilities](../../src/utils/fileUtils.ts)**: Path manipulation, hidden file detection, glob pattern matching.
+- **[Sync Module](../../src/extension.ts)**: Integrated into main extension activation, reveals active file in tree with configurable delay, respects visibility state.

-This diagram shows the main modules and their interactions. The Scanner/Indexer discovers files, which are passed to the TreeDataProvider for display. The Preview/Open Controller manages file opening, and all modules use the Settings Manager and Utilities as needed. The Sync Module keeps the tree in sync with the active editor.
