-If you ordered a kit with per-key RGB, we will start by installing those. The LEDs are sensitive to heat and need to be installed in a specific way, so make sure to read the instructions below first.
+If you ordered a kit with per-key RGB, we will start by installing those. If you don't have LEDs, you can skip to the next section
 
--   Make sure to never stay on the same pad for more than 4 seconds with your soldering iron ! You might risk damaging the pad
--   If a pad doesn't want to be soldered, let it cool down for 30 seconds and then try again
+{: .warning }
+The LEDs need to be installed in a very specific way. Read the following instructions carefully first, and then install them. If you don't, they will not work ! 
 
--   The Gnd pad of the Led is the one with the cutout (top right pin on the picture)
--   The Gnd pad on the PCB is the one with the cutout, and white circle (top right on the picture)
 
-Install all the LEDs.

+Inspect the LED: there is one of the pins that has a slight chamfer in it. The plastic casing also has an indent. This is **the GROUND pin**.

+- Inspect the PCBs: for each LED footprint, there is one pin that has a white line next to it
+- **We need to match the chamfered pin of the LED, with the marked pin on the PCB**
+
+{: .warning }
+The LEDs are sensitive to heat. Stay at most 2 seconds on each pad. If that doesn't work, try slowly increasing the temperature of your soldering iron.
+
+- Install the LEDs on the same side as the other SMD components
+- Solder them pad by pad
+- Go through the LEDs one by one
