+
+Now you aren't satisfied with the number of keys you have? With switch matrices you can have more switches on less pins! (Wow this is a good sales pitch, hire me adafruit :3)
+
+First, open up your schematic and place the switches in a grid shape:
+
+<img src="/docs/v2/keymatrixschematic.png" className="max-w-96" />
+
+If you want a non-symetric shape for your keys, it's fine to delete any switch you don't want.
+
+Now add diodes. Their schematic name is `D`. Place them at one end of the switch (any end, but it should be the same for all the switches), **pointing away from the switch**:
+
+<img src="/docs/v2/keymatrixschematicdiode.png" className="max-w-96" />
+
+Now, connect each row of diode heads together to form a row, and connect the each row to a GPIO pin. Do the same with the each column of switches (on the side without the diode) to form a column. Connect each column to a GPIO pin too.
+
+<img src="/docs/v2/keymatrixschematicconnected.png" className="max-w-96" />
+
+Now you do the same things assigning the footprints, but for diodes you will use Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal as the footprint.
+

+
+Congrats! You got a working key matrix. Nothing really changed for the PCB routing part. Just as a side note, don't put the diodes directly on the switches (or they will collide in real life). I recommend putting them on the other side of the board (flip using F) and between the switches:

+Be sure to not use the built in footprint! The correct footprint should be called 128x64OLED.

 Here I will write out some tips and trics I learnt about in my designs. Feel free to add any of yours!
 
+- Google is your best friend, search up anything u don't know. (And the cake is a lie :P)
 - Spam vias everywhere! They are free.
 - Try routing everything on one layers first, if you can't without making a big loop, move to the second layer. This keeps your board clean.
 - Make multiple revisions! I rerouted my first macropad like 10 times while adding stuff.
