-* **/sctrack** to tracker a position, coordinates or a player
+* **/sctrack** to tracker a position, coordinates or a player (see below)

 You can use **/scompass-option** with arguments directly if you prefer (`/scompass-option <option> <type>`).

+## Trackers addons
+
+To use the command **sctrack**, you need at least one tracker addon. You can find them here:
+
+* [CoordsTracker](https://github.com/arboriginal/SCT-CoordsTracker): Allows to track specific coordinates.
+* [DeathPosTracker](https://github.com/arboriginal/SCT-DeathPosTracker): Allows to track the last death position.
+* [PapiPositionTracker](https://github.com/arboriginal/SCT-PapiPositionTracker): Allows to track positions defined using PlaholderAPI placeholders.
+* [PlayerTracker](https://github.com/arboriginal/SCT-PlayerTracker): Allows to track players positions.
+* [PositionTracker](https://github.com/arboriginal/SCT-PositionTracker): Allows to track static positions.
+
+Have a look at the [Spigot plugin thread](https://www.spigotmc.org/threads/simplecompass.351093/), maybe other addon (made by other developers) will be listed.
