I worked with a consultant using the lair framework two years ago and since then I have been a huge fan of the project to manage pentest information.
Tom Steele has done an amazing job with the project but it has been a pain to install but thanks to Ryan Hanson and Docker you can now setup a lair instance with 7 simple commands on a clean (digitalocean) Ubuntu 16.04 install:
curl -sSL https://get.docker.com/ | sh
curl -L https://github.com/docker/compose/releases/download/1.6.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
git clone https://github.com/ryhanson/lair-docker.git
From there you can start importing data with drones or entering it manually but with the installation bar lowered you do not have a reason to not give this amazing tool a try!
