Using this Pibow Touchscreen Frame is a breeze. First, take out the frame and the provided bolt pack. You can attach the three layers to the back of your 7 - inch Raspberry Pi Touchscreen without needing any tools. Just use the bolts from the pack. Then, set up the two legs to hold the screen at an ideal viewing angle for you to use. When using it, make sure not to apply excessive force on the frame or the screen. Avoid placing it in very humid or hot environments to prevent damage. To keep it in good condition, you can gently wipe it with a soft, dry cloth every once in a while. Remember, this frame doesn't come with the screen or the Raspberry Pi, it's just for mounting the screen.
