 - Overall layout: Where you want your connectors, buttons etc. dictates the layout. For now, the USB and PWM3389 is important, later buttons/wheels, additional LEDs etc. need to be carefully considered. Check, e.g., how mice sensors are typically placed relative to the center/hand placement.
 
-- Components are typically designed with layout in mind, consider the orientation/placement to reduce routing complexity. (E.g., inputs are grouped on one edge, outputs on another. Analog pins are grouped allowing to split ground planes etc.)
+- Components are typically designed with layout in mind, consider the orientation/placement to reduce routing complexity. (E.g., inputs are grouped on one edge, outputs on another, analog pins on a third etc., to facilitate the routing and improve signal integrity.)
   
 - Most datasheets will give an example layout for decoupling and interconnects, these are helpful to give an initial idea.

 ## 5) Cut-out for the PMW3389DM
 
-The sensor requires a cut-out, look in the data-sheet for exact dimensions. You can use the edge cut layer to make the cut out. Alternatively, you can make the edge cut a part of the footprint (but I have never done that, so not sure how hard it is, [see](https://forum.kicad.info/t/create-a-custom-shape-hole/12646)). Activate to `Show filled areas in zones`, to see verify that you don't pour copper under the the sensor.

A third alternative is to att the cut-out as a user layer in the footprint, just a guideline as to where to cut the PCB (in that case its just informative and does not have any meaning to KiCad.)

 ## 6) Design Rule Check (DRC)
 
-The Design Rule Check give you warnings if you don’t comply with the Design rules that you previously setup. It will give you warnings on short circuits, clearance issues etc..
