Open-source appropriate technology is when people are able to design and create technology that is helpful and can be used by people around the world. This technology is meant to help people with everyday tasks and problems. It is important to make sure that this technology is accessible and easy to use, so it can benefit people with limited resources. People are free to share the designs and instructions for making the technology, so that it can be used by anyone interested in making it. By sharing the designs and instructions openly, more people can be helped through the technology.
