Add parameter description for custom python tools within the script

Question asked by Ananya_clark on Nov 1, 2017

I have developed a python toolbox (.pyt) with a couple of scripts as individual tools. I would like to develop Help or tool descriptions for each of the tools, so that when a user clicks on any parameter on the tools, the right side of the tool window gives out a description/explanation of the parameter just like a default ArcGIS tool displays (shown in the picture  below).

 

How can I achieve this same functionality in my custom toolbox scripts? I know how to do it through ArcCatalog, but I want to achieve this within the script itself.

 

Thanks
