 ## Post-Lab Extra Assignment
 
-This semester, we are going to use a tool called **Altium**.  We are also going to work with schematics a LOT.  Instead of hand drawing all of the schematics, we are going to draw them in Altium.  Therefore, as part of our first lab, we are going to have you do an exercise that walks you through how to draw a simple schematic in Altium.  This is a separate submission on Canvas, with details on how to complete it [here](../lab-1.md).
