Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a [commit status](https://help.github.com/articles/about-statuses/) is reported on all branches. This is required by Greenkeeper because we are using your CI build statuses to figure out when to notify you about breaking changes.

Since we did not receive a CI status on the [`greenkeeper/initial`](https://github.com/axetroy/react-time-diff/commits/greenkeeper/initial) branch, we assume that you still need to configure it.

If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with `greenkeeper/`.

We recommend using [Travis CI](https://travis-ci.org), but Greenkeeper will work with every other CI service as well.

まず、リポジトリの CI 設定と、greenkeeper/initial ブランチについて報告されたステータスを確認します。すべてのブランチで CI のコミットステータスが報告されるか、greenkeeper/ で始まるブランチが明示的に対象となっていれば完了です。
