+# An example .gitlab-ci.yml file to test (and optionally report the
+# coverage results of) your [Julia][1] packages. Please refer to the
+# [documentation][2] for more information about package development in
+# Julia.
+#
+# Here, it is assumed that your Julia package is named
+# `MyPackage`. Change it to whatever name you have given to your

+# - Navigating to the `CI/CD Pipelines` settings of your project,
+# - Copying and pasting the default `Simplecov` regex example
+#   provided, i.e., `\(\d+.\d+\%\) covered` in the `test coverage
+#   parsing` textfield.
