 ## Known issues and limitations
 
+### Currently OS X and Linux only
+
+This action has not been tested for the Windows virtual environment. If you can provide the steps necessary to setup (even install?) OpenSSH on the Windows machine, please open an issue. 
+
 ### Works for the current job only
 
 Since each job [runs in a fresh instance](https://help.github.com/en/articles/about-github-actions#job) of the virtual environment, the SSH key will only be available in the job where this action has been referenced. You can, of course, add the action in multiple jobs or even workflows. All instances can use the same `SSH_PRIVATE_KEY` secret.
