Adds install instructions and CI

[LSaldyt]

Not the biggest change.. but install instructions seem crucial ;).

Thank you for proposing this. I cannot merge it unfortunately as is because

• the code base is maintained on bitbucket rather than github. This is just an automatic mirror of the repository.
• pull requests should be issued to the development rather than the master branch. The master branch is for releases and release tags only.

This was just a test to see how active the repository was. Is the bitbucket version accepting PRs to the dev branch?

[dtolpin]

Yes, gladly. And CI is most welcome.

I'll keep it open until I figure out how to merge on github and synchronize both repos properly. Thank you for the contribution.
