Adding Info to Parameters in Model Builder

[ChadHarris17]

Hello, 

New to the community and new to GIS so please excuse any poor terminology or oversights.

I am currently working within model builder and hoping to build a custom tool that others can use to run my process of converting a standardized excel table to KMZ.

My tool works fine but I am wondering how, if possible, can I add descriptions/information to the parameters in my model for potential users to read?

For example, I want the user to know when entering the date (string) that they need to enter it in YYYYMMDD format.

I am 90% sure it can be done as I have used other peoples custom tools that have descriptions, but I can't seem to find any information elsewhere and have exhausted my ideas of where to look within the application.

Thank you for any help.

Amazing, thank you! I was getting as far as editing the description in the properties and never would have thought what I was looking for would be in the metadata.

Cheers.
