How to install Ansible on Debian Jessie

I'm starting with fresh minimal netinst Debian jessie.

1. Add ubuntu package repository from where ansible will be installed (don't worry, it is official way of installing ansible on debian)
   
   echo "deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main" >> /etc/apt/sources.list
   
2. Install ansible
   
   apt-get update
   apt-get install ansible
   
3. Verify installation
   
   ansible --version
