+# BEFORE YOU DO ANYTHING, READ THIS FIRST.
+
+**Do not flash new firmware until you've verified that the electronics are all working.**
+
+That means, finish building the trackball, plug it in, use the stock firmware for about five minutes. Verify that the cursor is moving.
+
+Once you've verified that it all works, you're good to go flashing new firmware.
+
+## Main Instructions
+
+**TODO photo of all parts in the kit**
+
+In this section, you'll go over how to build a Trackball Nano from the official Ploopy Nano Trackball kit.
+
+Note that some of these pictures were taken at different times, so they may show a bit of inconsistency in between steps.
+
+## Step X: Get the necessary tools
+
+**TODO photo of all tools**
+
+- 2.5mm Allen key or screwdriver (comes with your kit)
+- Soldering iron
+- Solder
+
+## Step X: Remove support material from 3D-printed parts
+
+**TODO photo of top with support material**
+
+The top has support material that must be removed prior to use.
+
+"Support material" is more hollow than the structural plastic. You'll have to remove it before you continue with the assembly.
+
+Most of the time, it can be removed using nothing but your fingers. If you find a bit of support material is sticking, use a pair of pliers or tweezers to scrape it off. Be careful not to damage the parts as you remove the support material.
+
+**TODO create video removing support material**
+[Here's a video on removing support material.](**TODO**)
+
+## Step X: Solder ADNS-5050 sensor to printed circuit board
+
+**TODO create video of ADNS-5050 being soldered**
+
+**MAKE SURE THAT THE ADNS-5050 IS ORIENTED CORRECTLY BEFORE YOU SOLDER IT!** This is a really easy step to mess up, so *DOUBLE-CHECK IT!*
+
+## Step X: Place printed circuit board into base
+
+**TODO photo of PCB in base**
+
+## Step X: Place ADNS-5050 sensor optic on printed circuit board
+
+**TODO photo of sensor optic placed down
+
+## Step X: Place top onto base
+
+**TODO photo of top placed onto base**
+
+The top should slide onto the base without any force required at all. You might have to push it down **a little tiny bit**, but if you have to bend things hard, something is wrong. Go back a few steps and see if anything is missing or misaligned.
+
+## Step X: Screw top into base
+
+**TODO photo of screws applied to base**
+
+## Step X: Apply friction pads to base
+
+**TODO friction pads applied to base**
+
+## Step X: Prepare bearing press jig

+
+Prepare the following components:
+
+- Bearing press jig
+- 3x roller bearing
+- 3x roller bearing dowel
+
+## Step X: Insert roller bearing and roller bearing dowel into bearing press jig

+
+## Step X: Press the bearing press jig together

+
+This may require a surprising amount of force. Try your best not to bend the roller bearing dowel, but if you do, there should be spares with your kit parts.
+
+## Step X: Remove bearing from bearing press jig and repeat

+
+At the end, all of your bearings should look like this.

+- Ensure that the bearings are pressed all the way into the case. If the bearings aren't seated all the way, there's a good chance that the ball will become badly scratched.
+- Needle nose pliers or some similar tool can be used to ensure that the bearing is fully seated.
+
+## Step X: Insert the ball
+
+**TODO photo of ball in top**
+
+Depending on slight size variations, you might need to push the ball in with some force, but it shouldn't require a large amount of force.
+
+## Step X: Verify that the Ploopy Nano Trackball is working correctly
+
+Plug the trackball into your computer. If you move the ball, it should move the cursor.
+
+## Step X: Spin the ball to break in the bearings
+
+The bearings are a bit scratchy when they're new. To prevent them from jumping around during initial use, spin the ball with some Latin dance vigour for about three minutes. That should be enough to break them in.
+
+The bearings will take about a week to become fully broken-in.
+
+## Step X: All done!
+
+Congrats, you finished building the Ploopy Nano Trackball!
+
+It's done! Love it, use it, but don't you dare abuse it!
