-# Auto-Import Implementation Summary
-
-## What was implemented:
-
-### 1. Dependencies (pyproject.toml)
-- Created `pyproject.toml` in `quiz/` directory
-- Added Django and watchdog dependencies
-- Configured for `uv` package manager
-
-### 2. Question Importer (quiz/utils/importer.py)
-- `ImportStats` class: Tracks import statistics including:
-  - Total files found
-  - MCQ vs non-MCQ questions
-  - Questions with answers vs TODO placeholders
-  - Created vs updated counts
-  - Per-folder completion statistics
-- `parse_markdown_question()`: Parses markdown files to extract:
-  - Question text
-  - Options (supports both `- A:` and `- A` formats)
-  - Correct answer from spoiler blocks
-  - Skips questions with "TODO" answers
-- `import_question_file()`: Imports a single question file
-- `import_questions()`: Bulk import with statistics
-- `delete_question_by_path()`: Removes deleted questions from database
-
-### 3. File System Watcher (quiz/utils/watcher.py)
-- `QuestionFileHandler`: Handles file system events with:
-  - 2-second debounce for file changes
-  - Auto-import on file create/modify
-  - Auto-delete on file removal
-  - Real-time console feedback
-- `QuestionWatcher`: Main watcher class using watchdog Observer
-- `start_watcher_thread()`: Starts watcher in background daemon thread
-  - Performs initial full import on startup
-  - Displays comprehensive statistics
-  - Continues watching for changes
-
-### 4. Django Integration
-- Updated `QuizAppConfig.ready()` in `apps.py`:
-  - Automatically starts watcher thread on Django startup
-  - Runs in daemon thread (doesn't block shutdown)
-  - Only runs in main process (not reloader)
-- Updated `import_questions` management command:
-  - Uses refactored importer
-  - Shows detailed statistics output
-- Added `QUESTION_WATCH_PATH` setting to `settings.py`
-
-## Current Statistics:
-```
-Total .md files found:     312
-MCQ questions found:       162
-Non-MCQ skipped:           152
-Questions with answers:    6
-Questions with TODO:       154
-Overall completion:        3.7%
-
-Completion by Exam Folder:
-2022-01-15             2/ 25 MCQ (  8.0%)
-2022-06-01             4/ 19 MCQ ( 21.1%)
-2023-01-11             0/ 17 MCQ (  0.0%)
-2023-05-31             0/ 10 MCQ (  0.0%)
-2024-01-10             0/ 14 MCQ (  0.0%)
-2024-05-29             0/ 14 MCQ (  0.0%)
-2025-01-15             0/ 16 MCQ (  0.0%)
-2025-02-08             0/ 16 MCQ (  0.0%)
-2025-06-03             0/ 16 MCQ (  0.0%)
-2025-08-08             0/ 15 MCQ (  0.0%)
-```
-
-## How it works:
-
-1. **On Django startup**:
-   - Background thread starts automatically
-   - Performs initial import of all questions
-   - Displays comprehensive statistics
-   - Begins watching for file changes
-
-2. **When you edit a question in Obsidian**:
-   - Watcher detects file change
-   - Waits 2 seconds (debounce multiple saves)
-   - Automatically imports/updates the question
-   - Shows console feedback
-
-3. **When you delete a question file**:
-   - Watcher detects deletion
-   - Removes question from database
-
-4. **Manual import**:
-   - Run: `python3 manage.py import_questions`
-   - Shows same detailed statistics
-
-## Future considerations:
-
-### Multi-select questions support:
-Currently the `Question.correct_answer` field is `max_length=1`, which only supports single answers. Many questions have "Välj två alternativ" and answers like "B och D" or "B, D".
-
-To support multi-select:
-1. Update `Question.correct_answer` to `max_length=50`
-2. Create Django migration
-3. Update `parse_markdown_question()` to extract multiple letters (e.g., "B och D" → "B,D")
-4. Update `views.py` answer validation to compare sorted comma-separated values
-5. Update quiz UI to allow selecting multiple options
-
-### Answer format normalization:
-Need to standardize multi-select answer format in Obsidian:
-- Current: "B och D", "B, D", "BD"
-- Recommended: "B,D" (sorted, comma-separated, no spaces)
-
-### Question types not yet supported:
-- `frågetyp/hotspot`: Image-based clickable questions
-- `frågetyp/dnd-text`: Drag-and-drop text matching
-- `frågetyp/textfält`: Free text input questions
-- `frågetyp/sammansatt`: Multi-part questions
-
-These are currently skipped during import.
-
-## Testing the implementation:
-
-1. **Start Django server**:
-   ```bash
-   cd /Users/johandahlin/dev/medical-notes/quiz
-   python3 manage.py runserver
-   ```
-   You'll see the initial import statistics on startup.
-
-2. **Test auto-import**:
-   - Open a question in Obsidian with "TODO" in spoiler block
-   - Replace "TODO" with a letter (e.g., "B")
-   - Save the file
-   - Check Django console for auto-import message
-
-3. **Test manual import**:
-   ```bash
-   python3 manage.py import_questions
-   ```
-
-4. **Check database**:
-   ```bash
-   python3 manage.py shell
-   >>> from quiz.models import Question
-   >>> Question.objects.count()
-   ```
