 ## Architecture
 ![](docs/ElekArch.png)
 
+_Elektron_ is comprised of three main components: _Task Queue_, _Scheduler_ and _Power Capper_.
+* **Task Queue** - Maintains tasks that are yet to be scheduled.
+* **Scheduler** - Matches tasks' resource requirements with Mesos resource offers. Tasks that matched offers are then launched on the corresponding nodes.
+* **Power Capper** - The Power Capper monitors the power consumption of the nodes in the cluster through the use of [Performance Co-Pilot](http://pcp.io/). A power capping policy uses this information and decides to power cap or power uncap one or more nodes in the cluster using [RAPL](https://01.org/blogs/2014/running-average-power-limit--rapl).
