Documentation regarding Trial period and linux usage

[asos-sasamilovic]

I would like to start using the docker version of the emulator, but am hestitant due to some concerns around the trial period issue. Also the documentation on this repo implies there is no linux version, but according to the documentation here there is.

I would like the documentation to mention the potential pitfalls of the trial issue and if there are any plans to remove this from the docker version of the emulator. I would also like the documentation to explain how to use the linux version of the emulator.
