+#### 1. Why does the Raspberry Pi remain unpowered after the PiSugar is turned on?
+
+The common cause of this issue is residual solder mask on the bottom of the Raspberry Pi's GPIO pins. You can gently scrape the solder points with a plastic tool to ensure a clean connection for the pogo pins. After that, try reinstalling the PiSugar on the bottom of the Raspberry Pi.

+#### 2. Can the PiSugar be used together with the official Raspberry Pi 5B cooling module?
+
+Yes, it can. However, the mounting clips of the official cooling module pass through the Raspberry Pi PCB and occupy some space at the bottom, which can interfere with the installation of the PiSugar. You simply need to modify the mounting clips as shown in the diagram, gently spread the legs of the plastic fasteners outwards, which allows for proper assembly of PiSugar.
