+# Contributing to AntiSSRF
+
+Thank you for your interest in contributing to the AntiSSRF project! This guide will help you get started.
+
+## Development Setup
+
+1. Clone the repository
+2. Install dependencies for your target language (C# or Node.js)
+3. Make your changes
+4. Test thoroughly
+5. Submit a pull request
+
+## Updating IP Address Ranges
+
+The IP address ranges are maintained in [`config/IPAddressRanges.json`](config/IPAddressRanges.json) and automatically generated into language-specific files.
+
+### Prerequisites
+Install `jq`: `brew install jq` (macOS) or `sudo apt-get install jq` (Linux)
+
+### Process
+1. **Edit** [`config/IPAddressRanges.json`](config/IPAddressRanges.json)
+2. **Regenerate** the code files:
+   ```bash
+   ./scripts/build-ip-ranges-nodejs.sh
+   ./scripts/build-ip-ranges-cs.sh
+   ```
+3. **Commit** all changes (JSON + generated files):
+   ```bash
+   git add config/IPAddressRanges.json nodejs/config/IPAddressRanges.ts csharp/config/IPAddressRanges.cs
+   git commit -m "Update IP address ranges"
+   ```
+
+**Important**: The GitHub Actions workflow will fail if generated files don't match the source JSON.
