The Leaderboard sample scene demonstrates the read, write and display of Leaderboard data. The sample scene doesn't use any custom code and works "code free" using standard Heathen tools.
The 3 buttons arranged above the display area simply call methods on the Leaderboard Manager to start query processes. The Leaderboard Manager's Evt Query Completed event will be raised as each query completes and will call the Leaderboard UI List's Display method causing the results to be displayed in the UI.
Located on the Canvas > Leaderboard Scroll View > Template > Leaderboard Entry UI Record GameObject. The Leaderboard Entry UI Record is instantiated by the Leaderboard UI List for each record it is provided.
At the bottom of the screen you will see a red box with a few few self explanatory buttons. Those buttons use the LeaderboardObject to clear or update the score of the user on the leaderboard in question.
To the right you will notice a display that updates in real time as the user's score is changed. The Developer Cheat Box > User Leaderboard Entry GameObject is using the LeaderboardUserEntry component to update the score and rank label's for the user on this board. This component reacts to changes on the board and updates the values as required and can be refreshed on demand if desired.
Assuming you are using an unmodified version of the sample scene and Steam Settings you will see messages appear in the Unity Editor Console log detailing each step of the initialization process.

The green buttons located at the top of the board allow you to query the boards top 10, to query only your friends or to query the entries near your own and are demonstrations of the various queries available all ran code free.
