Who is the device for? What problem does it solve?

[xtalax]

Hello all, firstly your work so far across all of your prosthetics looks amazing!

I'd like to suggest a change, and that is to recognize that you have multiple audiences, those being people who might want to help design devices like this, people who want to build your devices and people who are wondering if they could use your devices.

Your readme reads like it is aimed at the first, and that is fine, I'd like to propose that you add a few more introductions, catering to your other audiences. For example by answering the following questions:
Which body parts does a person need to have to use the device?
Which nervous system/muscular function does a person need to have to use the device?
What are some examples of people who might want to use the device?
Is the device 'finished', i.e. ready to build?
Which tools does someone need to build the device?
Which materials does someone need to build the device? - link to BOM
How does one build the device? - link to instructions
What can the device do?
What can't it do?

Thanks for your time, I hope you consider answering these questions important.
