Here's how I think is best:
1) Open your browser to http://helpx.adobe.com/creative-cloud/learn/start/photoshop.html
2) Download the sample file and unzip it.
2) Scroll down the page and watch the videos in order, optionally pausing the video to try it yourself in Photoshop CC
Please let me know how it goes.

Thank you. Will try that now and come back with result. Think I may be failing to unzip file. Have to google how to do that. Thanks again Randy.
