+## Code of Conduct
+
+By participating in this project, you commit to maintaining respectful interactions with all community members. Any form of insults, harassment, or other unacceptable behavior will not be tolerated.
+
+## Project Structure
+
+The project consists of the following main components:
+
+- **WeModPatcher** - Main project containing the patcher logic and user interface
+- **AsarSharp** - Library for working with ASAR archives (used for unpacking and modifying WeMod files)
+- **Core** - Core of the patcher, including static and dynamic patching
+- **Models** - Data models used in the project
+- **View** - User interface components
+
+## Development Environment Setup
+
+1. Clone the repository:
+   ```
+   git clone https://github.com/k1tbyte/Wemod-Patcher.git
+   ```
+
+2. Open the solution `Wemod-Patcher.sln` in Visual Studio or JetBrains Rider.
+
+3. Restore NuGet packages.
+
+4. Build the project.
+
+## Bug Reports
+
+If you've found a bug, please create an Issue with a detailed description:
+
+- WeMod Patcher version
+- WeMod version where the problem occurred
+- Detailed steps to reproduce the bug
+- Expected and actual behavior
+- Screenshots or error logs (if available)
+
+## Feature Suggestions
+
+Suggestions for new features or improvements are welcome! Create an Issue describing your idea, explaining:
+
+- What problem the proposed improvement solves
+- How you envision implementing this feature
+- Potential alternatives you've considered
+
+## Creating a Pull Request
+
+1. Fork the repository.
+2. Create a branch with a descriptive name:
+   ```
+   git checkout -b feature/feature-name
+   ```
+   or
+   ```
+   git checkout -b fix/fix-name
+   ```
+
+3. Make the necessary changes and commit with clear, descriptive messages.
+
+4. Ensure your code follows the project's style.
+
+5. Push the branch to your fork:
+   ```
+   git push origin your-branch-name
+   ```
+
+6. Create a Pull Request to the main repository.
+
+7. In the Pull Request description, explain the changes made and why they're necessary.
+
+## Code Style
+
+- Use C# naming conventions:
+  - PascalCase for class, method, and property names
+  - camelCase for local variables and parameters
+  - _camelCase for private fields
+
+- Add comments for complex code sections or patching methods
+
+- Follow SOLID and DRY principles
+
+## Testing
+
+Before submitting a Pull Request, ensure that:
+
+1. Your code compiles without errors
+2. You've manually tested the functionality
+3. The patch works with the current version of WeMod
+4. Changes don't break existing functionality
