-## Architecture

-An ongoing migration is moving all business logic into `rust/`. Each app under `apps/` is a UI shell — it owns rendering, interaction, and platform-specific concerns, but never owns logic. The UI framework for any given app is a replaceable detail.

 - Read components before using them. They may already apply classes, which affects what you need to pass and how to override them.

-Function signatures should make the call site readable and let the function evolve without breaking callers. Positional parameters fail both: `formatTime(30, 24)` hides which number is which, and adding, removing, or reordering an argument silently breaks every caller whose types happen to still line up. A single destructured object fixes both at once - each argument names itself at the call site, and the shape can grow without churn. So signatures default to one object parameter:
-
-```tsx
-// ❌ meaning depends on order; the shape can't evolve without touching every caller
-function formatTime(seconds: number, fps: number) { ... }
-
-// ✅ each argument names itself; fields can be added, reordered, or made optional freely
-function formatTime({ seconds, fps }: { seconds: number; fps: number }) { ... }
-```
-
-The one real exception is type predicates (`element is VideoElement`) — the language requires a positional subject, so the reasoning above doesn't get to apply.

+## Why?
+
+- **Privacy**: Your videos stay on your device
+- **Free features**: Most basic CapCut features are now paywalled 
+- **Simple**: People want editors that are easy to use - CapCut proved that
+
+## Features
+
+- Timeline-based editing
+- Multi-track support
+- Real-time preview
+- No watermarks or subscriptions
+- Analytics provided by [Databuddy](https://www.databuddy.cc?utm_source=opencut), 100% Anonymized & Non-invasive.
+- Blog powered by [Marble](https://marblecms.com?utm_source=opencut), Headless CMS.
+
+## Project Structure
+
+- `apps/web/` – Main Next.js web application
+- `apps/desktop/` – Native desktop app (in progress)
+- `src/components/` – UI and editor components
+- `src/hooks/` – Custom React hooks
+- `src/lib/` – Utility and API logic
+- `src/stores/` – State management (Zustand, etc.)
+- `src/types/` – TypeScript types
+
+## Getting Started
+
+### Prerequisites
+
+- [Bun](https://bun.sh/docs/installation)
+- [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/)
+
+> **Note:** Docker is optional but recommended for running the local database and Redis. If you only want to work on frontend features, you can skip it.
+
+### Setup
+
+1. Fork and clone the repository
+
+2. Copy the environment file:
+
+   ```bash
+   # Unix/Linux/Mac
+   cp apps/web/.env.example apps/web/.env.local
+
+   # Windows PowerShell
+   Copy-Item apps/web/.env.example apps/web/.env.local
+   ```
+
+3. Start the database and Redis:
+
+   ```bash
+   docker compose up -d db redis serverless-redis-http
+   ```
+
+4. Install dependencies and start the dev server:
+
+   ```bash
+   bun install
+   bun dev:web
+   ```
+
+The application will be available at [http://localhost:3000](http://localhost:3000).
+
+The `.env.example` has sensible defaults that match the Docker Compose config — it should work out of the box.
+
+### Desktop setup
+
+Desktop is opt-in. If you're only working on the web app, skip this entirely.
+
+If you want to get ready for `apps/desktop`, see [`apps/desktop/README.md`](apps/desktop/README.md). It's a two-step setup: Rust toolchain first, then desktop native dependencies.
+
+### Self-Hosting with Docker
+
+To run everything (including a production build of the app) in Docker:
+
+```bash
+docker compose up -d
+```
+
+The app will be available at [http://localhost:3100](http://localhost:3100).
+
+## Contributing
+
+We welcome contributions! While we're actively developing and refactoring certain areas, there are plenty of opportunities to contribute effectively.
+
+**🎯 Focus areas:** Timeline functionality, project management, performance, bug fixes, and UI improvements outside the preview panel.
+
+**⚠️ Avoid for now:** Preview panel enhancements (fonts, stickers, effects) and export functionality - we're refactoring these with a new binary rendering approach.
+
+See our [Contributing Guide](.github/CONTRIBUTING.md) for detailed setup instructions, development guidelines, and complete focus area guidance.
+
+**Quick start for contributors:**
+
+- Fork the repo and clone locally
+- Follow the setup instructions in CONTRIBUTING.md
+- Working on `apps/desktop`? See [`apps/desktop/README.md`](apps/desktop/README.md) for setup
+- Create a feature branch and submit a PR
