iFixit is a global community of people helping each other repair things. Anyone can create a repair manual for a device, and anyone can also edit the existing set of manuals to improve them. There is also an online shop for spare parts and tools. If your device, or problem to be fixed is not listed, you may start a question and wait for someone to come up with a solution to your problem. The site empowers individuals to share their technical knowledge with the rest of the world.
