-# Enforce Pull Request Description Length Action
+# AWS Credentials Rotation
 
-This action checks that a Pull Request Description is at a minimum length.  By default the minimum length is one.  If a different minimum length is needed it can be passed in using an Action Input. 
+This action rotates AWS Access Keys in your Action Secrets. In order for this action to work, valid AWS Access Keys and Secret Keys must already be in your Action Secrets.  The IAM User whose credentials are being rotated must also have permission to create and delete access keys. 
 
 ## Inputs
 
-### `minLength`
+### `GITHUB_TOKEN`
 
-A specific minimum length the description must be. 
+**Required** An access token used to authenticate with the Github API. 
+
+
+### `ACCESS_KEY_ID_SECRET_NAME`
+
+**Required** The name of an Actions Secret that stores the Access Key Id to rotate. 
+
+
+### `SECRET_ACCESS_KEY_SECRET_NAME`

+**Required** The name of an Actions Secret that stores the Secret Access Key to rotate. 
+
+### `IAM_USER_USERNAME`
