# Install MISP-maltego remote transform using ansible.
#
# DO NOT USE THIS UNLESS YOU REALLY KNOW YOU NEED THIS
# - Most people usually probably want to use the local transforms 
# - Others the 'ATT&CK - MISP' from the Transform Hub 
#
# First install your ubuntu system, 
# Then run ansible-playbook -i inventory.txt plume.yaml
#
# Then configure your iTDS server 
# - to create all the transforms and seeds and point to your docker.
# - export the objects, icons and machines to a mtz and associate to the seed
#   Paired Configurations:
#   - in Maltego > Export Config, and select
#   -- Entities > MISP
#   -- Icons > MISP + intelligence icons
#   -- Machines
#   Save as "paired_config.mtz", upload on TDS
