In the user's profile it is possible to add skills acquired with courses. The reasons to do so are various:
- users can be filtered by skills
 - courses can be sold to people with the necessary skills
 - creation of targeted marketing campaigns
 - creation of a skill history to monitor the progress of the person and the acquisition of new skills
 
In order to add skills, open the user's profile and click on Info -> Skills -> Add.
Please note that skills must be created in the Settings first (Settings -> List Values -> Skills)
