Using the Zebra Zero case for your Raspberry Pi Zero is super easy. First, take out the parts of the case. Place your Raspberry Pi Zero in the designated area within the case. Then, use the C4 nuts to hold the case together. You can insert the screws from either end of the nuts, which gives you flexibility. If you want to install a PiHAT, just secure it to the nuts on the other side. You can solder a GPIO header from either side of the board according to your needs. Remember, the Raspberry Pi Zero itself is not part of the package, so you'll need to provide that. This case is compatible with the Pi Zero v1.3 and the Pi Zero W as of July 29th, 2016. To maintain the case, simply use a dry cloth to wipe off any dust or dirt. Avoid using harsh chemicals as they might damage the wooden finish.
