How to build instructions?

[tchalvak]

In ubuntu 16.04 the pip installable version of pywatch fails on python3/python2 incompatibility (error message like "print must have parentheses).

So I came here to try to build pywatch directly, to see if a direct build would resolve the problem.

Any chance of getting build instructions in this repository?

For example, which python versions is pywatch compatible with? What commands should be run to get it set up? How can we set it as a globally available command?
