  -+https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-{version}.zip+]
  -(https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-{version}.zip.sha1[sha1])
  -
  -. Transfer the zip file to a temporary directory on the offline machine. (Do NOT
  -put the file in the {es} plugins directory.)
  -
  -. Run `bin/elasticsearch-plugin install` from the {es} install directory
  -and specify the location of the {xpack} zip file. For example:
