+Add `DroneCI` to a template's plugins to add a `.drone.yml` configuration file to
+generated repositories, and an appropriate badge to the README. The default configuration
+file supports Linux on ARM32 and ARM64.
+
+# Keyword Arguments
+* `config_file::Union{AbstractString, Nothing}=""`: Path to a custom `.drone.yml`.
+  If `nothing` is supplied, no file will be generated.
