+# ## Getting Started
+#
+# If using this component outside of the [Athena Framework][Athena::Framework], you will first need to add it as a dependency:
+#
+# ```yaml
+# dependencies:
+#   athena-console:
+#     github: athena-framework/console
+#     version: ~> 0.1.0
+# ```
+#
+# Then run `shards install`.
+#
+# From here you can then setup your entry point file talked about earlier, being sure to require the component via `require "athena-console"`.
+# Finally, create/require your `ACON::Command`s, and customize the `ACON::Application` as needed.
