Trezor agent installation instructions confusing

[doolio]

Is it trezor_agent or trezor-agent? Note the underscore vs the hyphen. I believe it is the latter.

Step 3 above suggests using $ pip3 install trezor_agent but PyPI suggests $ pip 3 install trezor-agent. This link also uses trezor_agent but is any case re-directed to trezor-agent.

There is reference to trezor_agent here, here and here.

Also, is this line $ pip3 install Cython hidapi necessary considering trezor[hidapi] is required in the trezor agent setup.py and you don't suggest it if installing from this repository. I believe Cython (or cython and/or cython3 to be explicit?) is a pre-requisite of trezor so is it not less confusing to list it as an OS dependency.
