ark get --help
# The get command downloads a CLI or application from the specific tool's releases or downloads page. 
# The tool is usually downloaded in binary format and provides a fast and easy alternative to a package manager.

# Usage:
#   arkade get [flags]

# Examples:
#   arkade get helm
#   arkade get linkerd2 --stash=false

# See which CLIs arkade can install:
ark get
# Use "arkade get TOOL" to download a tool or application:
# faas-cli
# helm
# kubectl

# k3d
# k3sup
# kubeseal
# inletsctl
# osm
# linkerd2
# kubebuilder
# kustomize
