mention git in readme dependencies

[veruu]

Since we mention python2 there, it would be a good idea to add git on the line. If someone tries to get skt working on a clean install, only by following the readme, they'd run into errors as they try to install skt from git since it's usually not installed on a bare system.

@veruu I followed the README.md document to try to install skt on my Fedora25 server via pip, no error was found while installing, but "skt" command is not available after installation.

I also tried to run "python3 setup.py build/install" to install skt, but that make no differnce.

Is there anything I can do to make skt work?

Hi @hengdinx ! A wild guess would be that pip is pointing to python2 on Fedora 25 and you have to use pip3 instead, or that the command is installed in a directory you don't have in $PATH. But without more info (python versions, pip version, exact commands and outputs etc.) I can't help you. Please open a different issue as your problem is unrelated to this one.
