+# ThrillWiki REST API
+
+A comprehensive API for amusement park, ride, and company data.
+
+## Features
+
+- **Companies**: Manufacturers, operators, and designers in the amusement industry
+- **Ride Models**: Specific ride models from manufacturers
+- **Parks**: Theme parks, amusement parks, water parks, and FECs
+- **Rides**: Individual rides and roller coasters
+
+## Authentication
+
+The API uses JWT (JSON Web Token) authentication for secure access.
+
+### Getting Started
+1. Register: `POST /api/v1/auth/register`
+2. Login: `POST /api/v1/auth/login` (returns access & refresh tokens)
+3. Use token: Include `Authorization: Bearer <access_token>` header in requests
+4. Refresh: `POST /api/v1/auth/token/refresh` when access token expires
+
+### Permissions
+- **Public**: Read operations (GET) on entities
+- **Authenticated**: Create submissions, manage own profile
+- **Moderator**: Approve/reject submissions, moderate content
+- **Admin**: Full access, user management, role assignment
+
+### Optional: Multi-Factor Authentication (MFA)
+Users can enable TOTP-based 2FA for enhanced security:
+1. Enable: `POST /api/v1/auth/mfa/enable`
+2. Confirm: `POST /api/v1/auth/mfa/confirm`
+3. Login with MFA: Include `mfa_token` in login request
+
+## Pagination
+
+List endpoints return paginated results:
+- Default page size: 50 items
+- Use `page` parameter to navigate (e.g., `?page=2`)
+
+## Filtering & Search
+
+Most list endpoints support filtering and search parameters.
+See individual endpoint documentation for available filters.
+
+## Geographic Search
+
+The parks endpoint includes a special `/parks/nearby/` endpoint for geographic searches:
+- **Production (PostGIS)**: Uses accurate distance-based queries
+- **Local Development (SQLite)**: Uses bounding box approximation
+
+## Rate Limiting
+
+Rate limiting will be implemented in future versions.
+
+## Data Format
+
+All dates are in ISO 8601 format (YYYY-MM-DD).
+All timestamps are in ISO 8601 format with timezone.
+UUIDs are used for all entity IDs.
