+# Contributing to pact_dart
+
+Thanks for contributing! Here’s how to get started:
+
+---
+
+## Run Tests
+
+1. Clone and create a new branch:
+
+```bash
+git clone https://github.com/pact-foundation/pact-dart.git
+cd pact-dart
+git checkout -b my-change
+```
+
+2. Install dependencies:
+
+```bash
+dart pub get
+dart run pact_dart:install
+# Or use custom lib download path
+PACT_DART_LIB_DOWNLOAD_PATH=. dart run pact_dart:install
+```
+
+3. Run tests:
+
+```bash
+dart test
+# Or use custom lib download path
+PACT_DART_LIB_DOWNLOAD_PATH=. dart test -j 1
+```
+
+## Generate Bindings with ffigen
+
+1. Download Pact FFI headers
+
+```bash
+# Ubuntu
+VERSION=0.4.27
+wget "https://github.com/pact-foundation/pact-reference/releases/download/libpact_ffi-v$VERSION/pact.h"
+# MacOS
+VERSION=0.4.27
+curl -O "https://github.com/pact-foundation/pact-reference/releases/download/libpact_ffi-v$VERSION/pact.h"
+# Windows
+$VERSION = "0.4.27"
+Invoke-WebRequest -Uri "https://github.com/pact-foundation/pact-reference/releases/download/libpact_ffi-v$VERSION/pact.h" -OutFile "pact.h"
+```
+
+2. Install LLVM
+
+```bash
+# Ubuntu
+sudo apt-get install libclang-dev
+# Windows
+winget install -e --id LLVM.LLVM
+# MacOS
+xcode-select --install
+```
+
+3. Regenerate bindings:
+
+```bash
+dart run ffigen
+```
+
+This will update the generated Dart bindings under `lib/gen/library.dart`.
