# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md){.internal-link target=_blank}.

## Developing

If you already cloned the <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.

### Virtual environment

                                                     property="doc.role" styleClass="form-control"
                                                     data-validation-help="1(username) | 2(groupname) | R(rolename)  e.g. Rguest"/>
                                    </div>
                                </div>
                                <div class="form-group row">

  - type: textarea
    id: version
    attributes:
      label: Version
      description: Include the output of `istioctl version`, `kubectl version --short`, and `helm version --short` (if you used Helm)
      placeholder: |
