In KnowledgeTree Manager, click into an asset. You will see a section labeled Description in the top right corner of your screen. Click the "edit pen" to edit the text.
Insert any asset description relevant to this content (ex: date, summary, etc). There is an option to bold, italicize, underline, bullet, and number the description entered. Save.
In Salesforce, reps can "hover" their mouse over an asset title and receive asset descriptions.
If no asset description is created for an asset, a rep will see the text "No description available" when they "hover" over an asset title.
