+# Contributing
+
+Thanks for your interest in contributing to this SDK! This document provides guidelines for contributing to the project.
+
+## Getting Started
+
+### Prerequisites
+
+- Go 1.21+
+- Docker (only required to run wire tests; see [Wire Tests](#wire-tests))
+
+### Installation
+
+Install the project dependencies:
+
+```bash
+go mod tidy
+```
+
+### Building
+
+Build the project:
+
+```bash
+go build ./...
+```
+
+### Testing
+
+Run the test suite:
+
+```bash
+go test ./...
+```
+
+#### Wire Tests
+
+If this SDK includes a `wiremock/` directory, the test suite contains wire tests that exercise the client against a [WireMock](https://wiremock.org/) server. The `go test` command above expects `WIREMOCK_URL` to point at a running WireMock instance.
+
+Start WireMock, run the tests, then tear it down:
+
+```bash
+docker compose -f wiremock/docker-compose.test.yml up -d
+export WIREMOCK_URL=http://localhost:$(docker compose -f wiremock/docker-compose.test.yml port wiremock 8080 | cut -d: -f2)
+go test ./...
+docker compose -f wiremock/docker-compose.test.yml down
+```
+
+The compose file maps WireMock's container port `8080` to a random host port, which is why `WIREMOCK_URL` is derived from `docker compose ... port` rather than hardcoded.
+
+### Formatting
+
+Format code:
+
+```bash
+gofmt -w .
+```
+
+Or equivalently:
+
+```bash
+go fmt ./...
+```
+
+### Vetting
+
+Run the Go vet tool to catch common mistakes:
+
+```bash
+go vet ./...
+```
+
+## About Generated Code
+
+**Important**: Most files in this SDK are automatically generated by [Fern](https://buildwithfern.com) from the API definition. Direct modifications to generated files will be overwritten the next time the SDK is generated.
+
+### Generated Files
+
+The following directories contain generated code:
+- Most Go files in the project
+
+### How to Customize
+
+If you need to customize the SDK, you have two options:
+
+#### Option 1: Use `.fernignore`
+
+For custom code that should persist across SDK regenerations:
+
+1. Create a `.fernignore` file in the project root
+2. Add file patterns for files you want to preserve (similar to `.gitignore` syntax)
+3. Add your custom code to those files
+
+Files listed in `.fernignore` will not be overwritten when the SDK is regenerated.
+
+For more information, see the [Fern documentation on custom code](https://buildwithfern.com/learn/sdks/overview/custom-code).
+
+#### Option 2: Contribute to the Generator
+
+If you want to change how code is generated for all users of this SDK:
+
+1. The Go SDK generator lives in the [Fern repository](https://github.com/fern-api/fern)
+2. Generator code is located at `generators/go-v2/`
+3. Follow the [Fern contributing guidelines](https://github.com/fern-api/fern/blob/main/CONTRIBUTING.md)
+4. Submit a pull request with your changes to the generator
+
+This approach is best for:
+- Bug fixes in generated code
+- New features that would benefit all users
+- Improvements to code generation patterns
+
+## Making Changes
+
+### Workflow
+
+1. Create a new branch for your changes
+2. Make your modifications
+3. Run tests to ensure nothing breaks: `go test ./...`
+4. Format your code: `gofmt -w .`
+5. Vet your code: `go vet ./...`
+6. Build the project: `go build ./...`
+7. Commit your changes with a clear commit message
+8. Push your branch and create a pull request
+
+### Commit Messages
+
+Write clear, descriptive commit messages that explain what changed and why.
+
+### Code Style
+
+This project uses `gofmt` for code formatting. Run `gofmt -w .` before committing to ensure your code meets the project's style guidelines.
+
+## Questions or Issues?
+
+If you have questions or run into issues:
+
+1. Check the [Fern documentation](https://buildwithfern.com)
+2. Search existing [GitHub issues](https://github.com/fern-api/fern/issues)
+3. Open a new issue if your question hasn't been addressed
