If you already know how to install python packages, then you can do:
$ pip install athenacli
You might need sudo, or you can install it in a virtualenv.
If you already know how to use docker, then you can do:
$ docker run --rm -ti -v $(pwd):/home/athena zzl0/athenacli athenacli
Note: we map the home directory (/home/athena) of docker container to current directory, athenacli will create a config file in it (.athenacli/athenaclirc), you might need to change some variables (please refer to quick start section of :doc:`index` page).
For MacOS users, you can also use Homebrew to install it:
$ brew install athenacli
