+Automatically close stale Issues and Pull Requests that tend to accumulate during a project.
+
+## How it works
+
+1. After a period of inactivity, a label will be applied to mark an issue as stale, and optionally a comment will be posted to notify contributors that the Issue or Pull Request will be closed.
+
+1. If the Issue or Pull Request is updated, or anyone comments, then the stale label is removed and nothing further is done until it becomes stale again.
+
+1. If no more activity occurs, the Issue or Pull Request will be automatically closed with an optional comment.
+
+## Installation
+
 After installing the integration, create `.github/stale.yml` in the default branch to enable it:
 
 ```yml
