+# Quiet Thanks
+
+A calm, private gratitude and mood log. No streaks, no gamification—just a simple way to reflect on what you're grateful for.
+
+## Features
+
+- **Quick check-in**: One prompt, optional mood, optional tags. Entry capture takes 10-20 seconds.
+- **Autosave**: No save button needed. Your entry saves automatically as you type.
+- **Timeline**: View all entries in reverse chronological order with filters.
+- **Weekly reflection**: See your entry count and top tags from the past 7 days.
+- **Export**: Download all entries as Markdown or JSON.
+- **Dark mode**: Calm, minimal interface with soft colors.
+- **Self-hosted**: Your data stays on your server.
+
+## Quick Start
+
+### Docker (Recommended)
+
+```bash
+docker compose up -d
+```
+
+The app will be available at `http://localhost:6124`.
+
+### Manual Setup
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Generate and run database migrations:
+   ```bash
+   npm run db:generate
+   npm run db:migrate
+   ```
+
+3. Start the development server:
+   ```bash
+   npm run dev
+   ```
+
+4. Open `http://localhost:3000` in your browser.
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Generate database migrations after schema changes
+npm run db:generate
+
+# Run migrations
+npm run db:migrate
+
+# Start dev server
+npm run dev
+
+# Build for production
+npm run build
+
+# Start production server
+npm start
+
+# View database with Drizzle Studio
+npm run db:studio
+```
+
+## Database
+
+- **Location**: `./data/quietthanks.db` (SQLite)
+- **Environment variable**: `DATABASE_PATH` to customize location
+- **Migrations**: Stored in `./drizzle/`
+
+The database is created automatically when you run migrations. In Docker, the `./data` directory is mounted as a volume to persist data.
+
+### Schema
+
+- **entries**: Main gratitude entries with date, text, optional mood (1-5), rough day flag, and timestamps
+- **tags**: Normalized tag names
+- **entry_tags**: Junction table linking entries to tags
+
+## Export
+
+Navigate to `/export` or use the Export tab to download your data:
+
+- **Markdown**: Human-readable format, grouped by date, includes mood and tags
+- **JSON**: Full data export with all fields and timestamps
+
+Exports include all entries regardless of filters.
+
+## Configuration
+
+### App Name
+
+Change the app name by editing `src/lib/constants.ts`:
+
+```typescript
+export const APP_NAME = "My Gratitude Log";
+```
+
+### Port
+
+In `docker-compose.yml`, change the port mapping:
+
+```yaml
+ports:
+  - "8080:3000"  # Change 8080 to your desired port
+```
+
+## Tech Stack
+
+- **Framework**: Next.js 16 with App Router
+- **Language**: TypeScript
+- **Styling**: Tailwind CSS 4
+- **Database**: SQLite with Drizzle ORM
+- **Icons**: Lucide React
+
+## Future Extension Points
+
+These features are not implemented but the architecture supports them:
+
+- **Cloud sync**: Add authentication and a sync service to enable cross-device access
+- **LLM summaries**: Integrate with an LLM API to generate monthly reflections
+- **Notifications**: Add push notifications for daily reminders
+- **Import**: Add an import endpoint to restore from JSON exports
