-7. Download the wheels from Travis-CI and Appveyor.

-   - Find the Appveyor build for the tag
-     [here](https://ci.appveyor.com/project/ddfisher/typed-ast-a4xqu/history) and

-     wheels](https://console.cloud.google.com/storage/browser/typed-ast) into the
-     `dist` directory.  (You will have to sign in with your Google account to
-     access these wheels, but all Google accounts have access.)
