+# Contributing to SleepPlugin
+
+Thank you for your interest in contributing to SleepPlugin! This document provides guidelines for contributing to the project.
+
+## How to Contribute
+
+### Reporting Bugs
+
+If you find a bug, please open an issue on GitHub with:
+- A clear, descriptive title
+- Steps to reproduce the issue
+- Expected behavior vs actual behavior
+- Your server version, plugin version, and Java version
+- Any relevant logs or error messages
+
+### Suggesting Features
+
+Feature suggestions are welcome! Please open an issue with:
+- A clear description of the feature
+- Why this feature would be useful
+- Any implementation ideas (optional)
+
+### Pull Requests
+
+1. **Fork the repository** and create your branch from `master`
+2. **Make your changes** following the code style guidelines below
+3. **Test your changes** on a local Paper server
+4. **Update documentation** if needed (README.md, CHANGELOG.md)
+5. **Commit your changes** with clear, descriptive commit messages
+6. **Push to your fork** and submit a pull request
+
+## Code Style Guidelines
+
+### Java Code Style
+
+- **Indentation**: 4 spaces (no tabs)
+- **Naming conventions**:
+  - Classes: `PascalCase`
+  - Methods: `camelCase`
+  - Variables: `camelCase`
+  - Constants: `UPPER_SNAKE_CASE`
+- **Braces**: Opening brace on same line
+- **Comments**: Use Javadoc for public methods, inline comments for complex logic
+- **Line length**: Try to keep lines under 120 characters
+
+Example:
+```java
+public class MyClass {
+    private static final int MAX_VALUE = 100;
+    private String myVariable;
+
+    /**
+     * Does something useful
+     * @param input the input parameter
+     * @return the result
+     */
+    public String doSomething(String input) {
+        if (input == null) {
+            return null;
+        }
+        return input.toUpperCase();
+    }
+}
+```
+
+### Configuration Files
+
+- **YAML files**: Use 2 spaces for indentation
+- **Comments**: Add comments for complex configurations
+- **Keys**: Use `kebab-case` for multi-word keys
+
+### Commit Messages
+
+Write clear, descriptive commit messages:
+- Use present tense ("Add feature" not "Added feature")
+- Keep first line under 50 characters
+- Add detailed description after blank line if needed
+
+Good examples:
+```
+Add storm skip functionality
+Fix null pointer in bed leave event
+Update documentation for custom languages
+```
+
+## Development Setup
+
+1. **Prerequisites**:
+   - Java 21 or higher
+   - Gradle 8.x (wrapper included)
+   - A Paper 1.21.5 test server
+
+2. **Clone and build**:
+   ```bash
+   git clone https://github.com/NovaDAndrew/sleep-plugin.git
+   cd sleep-plugin
+   ./gradlew build
+   ```
+
+3. **Test**:
+   - Copy `build/libs/SleepPlugin-*.jar` to your test server's `plugins/` folder
+   - Start the server and test your changes
+   - Check console for errors
+
+## Testing Guidelines
+
+Before submitting a pull request, test:
+- Plugin loads without errors
+- All features work as expected
+- No console errors or warnings
+- Config updates correctly
+- Language files load properly
+- Multi-world support works
+- Edge cases (1 player, odd numbers, etc.)
+
+## Adding Translations
+
+To add a new language:
+
+1. Copy `src/main/resources/lang/template.yml`
+2. Rename to your language code (e.g., `de_DE.yml`)
+3. Translate all message strings
+4. Test by setting `language: de_DE` in config.yml
+5. Submit a pull request with your translation
+
+## Documentation
+
+When making changes that affect:
+- **User-facing features**: Update README.md and modrinth.md
+- **Configuration**: Update config examples in documentation
+- **Breaking changes**: Add migration notes to CHANGELOG.md
