-        // Todo
+        // Lets you make players see a certain scoreboard and then a certain objective in that scoreboard.
+        //
+        // There are currently three slots where objectives can be displayed: in the sidebar on the right of
+        // the screen, below player names and in the player list that shows up when you press Tab. The names
+        // of these slots can be found here:
+        // http://jd.bukkit.org/rb/apidocs/org/bukkit/scoreboard/DisplaySlot.html
+        //
+        // Every objective has several lines of scores. Technically, the lines track players, but fake player
+        // names can be used by Denizen to let you call the lines anything you want.
+        //
+        // When using the sidebar as the display slot, all the scores set for an objective will be displayed
+        // there, but you will need to put actual player names in the lines to be able to use the below_name
+        // display slot (which displays each player's score underneath his/her name) and the player_list
+        // display slot (which displays each player's score to the right of his/her name in the player list).
+        //
+        // You can set scores manually, or you can use different Minecraft criteria that set and update the
+        // scores automatically. A list of these criteria can be found here:
+        // http://minecraft.gamepedia.com/Scoreboard#Objectives
+        //
+        // You can use the "remove" argument to remove different parts of scoreboards. The more arguments
+        // you use with it, the more specific your removal will be. For example, if you only use the "remove"
+        // argument and the "id" argument, you will completely remove all the objectives in a scoreboard,
+        // but if you specify an objective as well, you will only delete that one objective from that
+        // scoreboard, and if you also specify certain lines, you will only delete those specific lines from
+        // that objective. Similarly, if you use the "remove" argument along with the "id" and "viewers"
+        // arguments, you will only remove those viewers from the scoreboard, not the entire scoreboard.
