+# Contributing
+
+Thanks for your interest in contributing to this SDK! This document provides guidelines for contributing to the project.
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 20 or higher
+- pnpm package manager
+
+### Installation
+
+Install the project dependencies:
+
+```bash
+pnpm install
+```
+
+### Building
+
+Build the project:
+
+```bash
+pnpm build
+```
+
+### Testing
+
+Run the test suite:
+
+```bash
+pnpm test
+```
+
+Run specific test types:
+- `pnpm test:unit` - Run unit tests
+- `pnpm test:wire` - Run wire/integration tests
+
+### Linting and Formatting
+
+Check code style:
+
+```bash
+pnpm run lint
+pnpm run format:check
+```
+
+Fix code style issues:
+
+```bash
+pnpm run lint:fix
+pnpm run format:fix
+```
+
+Or use the combined check command:
+
+```bash
+pnpm run check:fix
+```
+
+## 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:
+- `src/api/` - API client classes and types
+- `src/serialization/` - Serialization/deserialization logic
+- Most TypeScript files in `src/`
+
+### 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 TypeScript SDK generator lives in the [Fern repository](https://github.com/fern-api/fern)
+2. Generator code is located at `generators/typescript/sdk/`
+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: `pnpm test`
+4. Run linting and formatting: `pnpm run check:fix`
+5. Build the project: `pnpm build`
+6. Commit your changes with a clear commit message
+7. 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 automated code formatting and linting. Run `pnpm run check:fix` 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

+## Streaming Response
+
+Some endpoints return streaming responses instead of returning the full response at once.
+The SDK uses async iterators, so you can consume the responses using a `for await...of` loop.
+
+```typescript
+import { LatticeClient } from "@anduril-industries/lattice-sdk";
+
+const client = new LatticeClient({ token: "YOUR_TOKEN" });
+const response = await client.entities.streamEntities();
