Documentation lacks examples and man page

[gnbl]

https://github.com/espeak-ng/espeak-ng#documentation refers to https://github.com/espeak-ng/espeak-ng/blob/master/docs/index.md but neither provide usage info or examples.
No man pages online yet either.

So here it goes. Man page:

[casualdegenerate]

There is no documentation on what certain arguments are, such as -d --device
All I want is to know how to set the --device to a sink so I can use it with what I made.
