 ## Requirements
 
 NodeJS is required for this action to run. This runs without issue on all GitHub hosted runners but if you are running into issues with this on self hosted runners ensure NodeJS is installed.

+
+## **Ownership**
+
+As of 2022/02/15 ownership of this project has been transferred to my personal account `nick-fields` from my work account `nick-invision` due to me leaving InVision. I am the author and have been the primary maintainer since day one and will continue to maintain this as needed.
+
+Existing workflow references to `nick-invision/retry@<whatever>` no longer work and must be updated to `nick-fields/retry@<whatever>`.
