+# 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()
+   ```
