+# Contributing to Acode
+
+Thank you for your interest in contributing to Acode! This guide will help you get started with development.
+
+## Quick Start Options
+
+### Option 1: DevContainer (Recommended)
+
+1. Install the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) in VS Code or other editors that support DevContainers.
+
+2. Clone and open the repository:
+   ```bash
+   git clone https://github.com/Acode-Foundation/Acode.git
+   code Acode
+   ```
+
+3. When VS Code prompts "Reopen in Container", click it
+   - Or use Command Palette (Cmd/Ctrl+Shift+P) → "Dev Containers: Reopen in Container"
+
+4. Wait for the container to build (~5-10 minutes first time, subsequent opens are instant)
+
+5. Once ready, build the APK:
+   ```bash
+   pnpm run build paid dev apk
+   ```
+
+   > Use any package manager (pnpm, bun, npm, yarn, etc.)
+
+### Option 2: Docker CLI (For Any Editor)
+
+If your editor doesn't support DevContainers, you can use Docker directly:
+
+```bash
+# Clone the repository
+git clone https://github.com/Acode-Foundation/Acode.git
+cd Acode
+
+# Build the Docker image from our Dockerfile
+docker build -t acode-dev .devcontainer/
+
+# Run the container with your code mounted
+docker run -it --rm \
+  -v "$(pwd):/workspaces/acode" \
+  -w /workspaces/acode \
+  acode-dev \
+  bash
+
+# Inside the container, run setup and build
+# bun run setup && bun run build paid dev apk
+pnpm run setup
+pnpm run build paid dev apk # or pnpm run build p d
+```
+
+**Keep container running for repeated use:**
+```bash
+# Start container in background
+docker run -d --name acode-dev \
+  -v "$(pwd):/workspaces/acode" \
+  -w /workspaces/acode \
+  acode-dev \
+  sleep infinity
+
+# Execute commands in the running container
+docker exec -it acode-dev bash -c "pnpm run setup"
+docker exec -it acode-dev pnpm run build paid dev apk
+
+# Stop and remove when done
+docker stop acode-dev && docker rm acode-dev
+```
+
+---
+
+## 🛠️ Manual Setup (Without Docker)
+
+If you prefer not to use Docker at all:
+
+### Prerequisites
+
+| Requirement | Version |
+|------------|---------|
+| **Node.js** | 18+ (22 recommended) |
+| **pnpm** or **bun** | Latest |
+| **Java JDK** | 17+ (21 recommended) |
+| **Android SDK** | API 35 | 
+| **Gradle** | 8.x |
+
+### Environment Setup
+
+Add these to your shell profile (`~/.bashrc`, `~/.zshrc`, or `~/.config/fish/config.fish`):
+
+**macOS:**
+```bash
+export ANDROID_HOME="$HOME/Library/Android/sdk"
+export PATH="$PATH:$ANDROID_HOME/platform-tools:$ANDROID_HOME/cmdline-tools/latest/bin"
+```
+
+**Linux:**
+```bash
+export ANDROID_HOME="$HOME/Android/Sdk"
+export PATH="$PATH:$ANDROID_HOME/platform-tools:$ANDROID_HOME/cmdline-tools/latest/bin"
+```
+
+Some more environment variables, check [cordova docs](https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html).
+
+### Build Steps
+
+```bash
+# Clone the repository
+git clone https://github.com/Acode-Foundation/Acode.git
+cd Acode
+
+# Install dependencies and set up Cordova
+pnpm run setup
+
+# Build the APK
+pnpm run build paid dev apk # or pnpm run build p d
+```
+
+The APK will be at: `platforms/android/app/build/outputs/apk/debug/app-debug.apk`
+
+
+## 📝 Contribution Guidelines
+
+### Before Submitting a PR
+
+1. **Fork** the repository and create a branch from `main`
+2. **Make changes** - keep commits focused and atomic
+3. **Check code quality:**
+   ```bash
+   pnpm run check
+   ```
+4. **Test** on a device or emulator if possible
+
+### Pull Request Checklist
+
+- [ ] Clear description of changes
+- [ ] Reference to related issue (if applicable)
+- [ ] Screenshots/GIFs for UI changes
+- [ ] Passing CI checks
+
+### Code Style
+
+We use [Biome](https://biomejs.dev/) for linting and formatting:
+- Run `pnpm run check` before committing
+- Install the Biome VS Code extension for auto-formatting
+
+### Commit Messages
+
+Use clear, descriptive messages:
+```
+feat: add dark mode toggle to settings
+fix: resolve crash when opening large files
+docs: update build instructions
+refactor: simplify file loading logic
+```
+
+## 🌍 Adding Translations
+
+1. Create a JSON file in `src/lang/` (e.g., `fr-fr.json` for French)
+2. Add it to `src/lib/lang.js`
+3. Use the translation utilities:
+   ```bash
+   pnpm run lang add       # Add new string
+   pnpm run lang remove    # Remove string
+   pnpm run lang search    # Search strings
+   pnpm run lang update    # Update translations
+   ```
