Installation guide

[June-Yann]

Would you mind putting the detailed installation guide for macOS, Windows and Ubuntu in the Readme file? I have some hard time getting the software installed.

If you simply want to use the software, please download the release packages for Mac and Windows here: https://github.com/lcbb/athena/releases . For these packages you just download, unzip, and run the included executables.

If you're interested in setting up a development environment to make your own version of Athena, please refer to HACKING.txt.

Note that Ubuntu is not supported. (The GUI will probably run fine on Ubuntu, but the sequence tools will not be available on that platform.)
