+###Examples
+####Leaderboard
+Included in the OSX-Sample is an example application of a bot you might make using SlackKit. It’s a basic leaderboard scoring bot, in the spirit of [PlusPlus](https://plusplus.chat).
+
+To configure it, enter your bot’s API token in `AppDelegate.swift` for the Leaderboard bot:
+
+```swift
+let learderboard = Leaderboard(token: "SLACK_AUTH_TOKEN")
+```
+
+It adds a point for every `@thing++`, subtracts a point for every `@thing--`, and shows a leaderboard when asked `@botname leaderboard`.
