+# Contributing to MongoDB OpenAPI Project
+
+## Development Setup
+
+### Prerequisites
+
+- Node.js v20 or later
+- npm v8 or later
+- Git
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/your-username/mongodb-openapi.git
+   cd mongodb-openapi
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Set up Git hooks (optional):
+   ```bash
+   npm run precommit
+   ```
+
+This will install Husky, which manages Git hooks for the project. The hooks ensure code quality by automatically running various checks before commits.
+
+## Development Workflow
+
+### Git Hooks
+
+This project uses the following Git hooks:
+
+- **pre-commit**: Automatically formats your code using Prettier and runs tests for staged JavaScript files to ensure code quality before each commit.
+
+### Available Scripts
+
+- `npm run format` - Format all files with Prettier
+- `npm run format-check` - Check formatting without modifying files
+- `npm run lint-js` - Lint JavaScript files
+- `npm run test` - Run all tests
+
+#### IPA specific targets
+
+- `npm run gen-ipa-docs` - Generate IPA ruleset documentation (see `./tools` folder for more information)
+- `npm run ipa-validation` - Run OpenAPI validation with Spectral
