 There are two main modes to usage: `local` or `remote`. By default Dodo works in the `remote` mode, meaning it assumes that the Twitter OSS dependencies are meant to be downloaded from their remote locations in [Github](https://github.com/twitter).

-Additionally, in `remote`-mode Dodo attempts to cache commands it has run against the local SHA. If it finds that it has run the given commands against the currently cached SHA for a repository it will not run them again. See the [Clean Up](#clean-up) section for more information.
