# Reference

This section provides the reference material for the Flyte SDK and CLI.

To get started, add `flyte` to your project

```shell
$ uv pip install --no-cache --upgrade flyte
```

This will install both the Flyte SDK and CLI.

### [Flyte SDK](https://www.union.ai/docs/latest/flyte/api-reference/flyte-sdk/page.md)

The Flyte SDK provides the core Python API for building workflows and apps on your Union instance.

### [Flyte CLI](https://www.union.ai/docs/latest/flyte/api-reference/flyte-cli/page.md)

The Flyte CLI is the command-line interface for interacting with your Union instance.

### [Flyte agent plugins](https://www.union.ai/docs/latest/flyte/api-reference/agent-plugins/page.md)

A portable agent-harness plugin — skills and MCP servers for authoring, migrating, and deploying Flyte with an AI agent.
