+## How to deploy?
 **Gitploy provides an intuitive UI that allows users to deploy a specific `ref`.** The UI provides three types of `ref`: *commit*, *branch*, and *tag*. The UI shows a list of options for each type. For example, the UI shows the current commit list with information such as SHA, description, committer if the user selects a commit.
 
 When the user selects `ref`, an icon indicating the commit's status appears on the right, and you can check the subset of contexts by clicking the icon. This information can be handy if you use the `required_contexts` field, which specifies a subset of contexts that must be `success`.
