+# GitHub Action for Assignee to Reviewer
+
+If your team currently uses pull request Assignees but would like to switch to  [Review Requests](https://blog.github.com/2016-12-07-introducing-review-requests/), having everyone change their workflows can be difficult. This GitHub Action eases the transition by automatically creating and removing review requests based on Assignees.
+
+## Usage
+
+This Action is used by subscribing to [Issues events](https://developer.github.com/v3/activity/events/types/#issuesevent) which are triggered whenever Assigness are added or removed.
+
+```workflow
+workflow "Assign reviewers based on assignees" {
+  on = "pull_request"
+  resolves = ["Assignee to reviewer"]
+}
+
+action "Assignee to reviewer" {
+  uses = "pullreminders/assignee-to-reviewer-action@master"
+  secrets = [
+    "GITHUB_TOKEN"
+  ]
+}
+```
+
