 If you have a *private repository*, this Action also requires you to [provide an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include up to four additional inputs to customize the upload context. **For public repositories, no token is needed**
