+# Contributing to CloudCLI UI
+
+Thanks for your interest in contributing to CloudCLI UI! Before you start, please take a moment to read through this guide.
+
+## Before You Start
+
+- **Search first.** Check [existing issues](https://github.com/siteboon/claudecodeui/issues) and [pull requests](https://github.com/siteboon/claudecodeui/pulls) to avoid duplicating work.
+- **Discuss first** for new features. Open an [issue](https://github.com/siteboon/claudecodeui/issues/new) to discuss your idea before investing time in implementation. We may already have plans or opinions on how it should work.
+- **Bug fixes are always welcome.** If you spot a bug, feel free to open a PR directly.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) 22 or later
+- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) installed and configured
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork:
+   ```bash
+   git clone https://github.com/<your-username>/claudecodeui.git
+   cd claudecodeui
+   ```
+3. Install dependencies:
+   ```bash
+   npm install
+   ```
+4. Start the development server:
+   ```bash
+   npm run dev
+   ```
+5. Create a branch for your changes:
+   ```bash
+   git checkout -b feat/your-feature-name
+   ```
+
+## Project Structure
+
+```
+claudecodeui/
+├── src/              # React frontend (Vite + Tailwind)
+│   ├── components/   # UI components
+│   ├── contexts/     # React context providers
+│   ├── hooks/        # Custom React hooks
+│   ├── i18n/         # Internationalization and translations

+├── shared/           # Code shared between client and server
+└── public/           # Static assets, icons, PWA manifest
+```
+
+## Development Workflow
+
+- `npm run dev` — Start both the frontend and backend in development mode
+- `npm run build` — Create a production build
+- `npm run server` — Start only the backend server
+- `npm run client` — Start only the Vite dev server
+
+## Making Changes
+
+### Bug Fixes
+
+- Reference the issue number in your PR if one exists
+- Describe how to reproduce the bug in your PR description
+- Add a screenshot or recording for visual bugs
+
+### New Features
+
+- Keep the scope focused — one feature per PR
+- Include screenshots or recordings for UI changes
+
+### Documentation
+
+- Documentation improvements are always welcome
+- Keep language clear and concise
+
+## Commit Convention
+
+We follow [Conventional Commits](https://conventionalcommits.org/) to generate release notes automatically. Every commit message should follow this format:
+
+```
+<type>(optional scope): <description>
+```
+
+Use imperative, present tense: "add feature" not "added feature" or "adds feature".
+
+### Types
+
+| Type | Description |
+|------|-------------|
+| `feat` | A new feature |
+| `fix` | A bug fix |
+| `perf` | A performance improvement |
+| `refactor` | Code change that neither fixes a bug nor adds a feature |
+| `docs` | Documentation only |
+| `style` | CSS, formatting, visual changes |
+| `chore` | Maintenance, dependencies, config |
+| `ci` | CI/CD pipeline changes |
+| `test` | Adding or updating tests |
+| `build` | Build system changes |
+
+### Examples
+
+```bash
+feat: add conversation search
+feat(i18n): add Japanese language support
+fix: redirect unauthenticated users to login
+fix(editor): syntax highlighting for .env files
+perf: lazy load code editor component
+refactor(chat): extract message list component
+docs: update API configuration guide
+```
+
+### Breaking Changes
+
+Add `!` after the type or include `BREAKING CHANGE:` in the commit footer:
+
+```bash
+feat!: redesign settings page layout
+```
+
+## Pull Requests
+
+- Give your PR a clear, descriptive title following the commit convention above
+- Fill in the PR description with what changed and why
+- Link any related issues
+- Include screenshots for UI changes
+- Make sure the build passes (`npm run build`)
+- Keep PRs focused — avoid unrelated changes
+
+## Releases
+
+Releases are managed by maintainers using [release-it](https://github.com/release-it/release-it) with the [conventional changelog plugin](https://github.com/release-it/conventional-changelog).
+
+```bash
+npm run release           # interactive (prompts for version bump)
+npm run release -- patch  # patch release
+npm run release -- minor  # minor release
+```
+
+This automatically:
+- Bumps the version based on commit types (`feat` = minor, `fix` = patch)
+- Generates categorized release notes
+- Updates `CHANGELOG.md`
+- Creates a git tag and GitHub Release
+- Publishes to npm

-For a quick solution, you can:
-1. Create a simple square PNG icon (512x512)
-2. Use online tools like realfavicongenerator.net to generate all sizes
-3. Or use ImageMagick: `convert icon-512x512.png -resize 192x192 icon-192x192.png`
