Custom Widget Leaderboard

Hi, I am delighted with this plugin, and I just need to polish their integration into my website with the following:
I need a widget that shows the 5 or 6 top ranking.
fields displayed are: Position, avatar, name (with buddypress profile link) and points.
I’m not a programming expert and so I ask for help, after having looked around everywhere looking for documentation to customize the widget leaderboard featuring plugin.

Thank you very much in advance.
