+      # [https://chris.beams.io/posts/git-commit/] -> https://cbea.ms/git-commit/
+      #
+      # 1. Separate subject from body with a blank line
+      # 2. Limit the subject line to 50 characters
+      # 3. Capitalize the subject line
+      # 4. Do not end the subject line with a period
+      # 5. Use the imperative mood in the subject line
+      # 6. Wrap the body at 72 characters
+      # 7. Use the body to explain *what* and *why* vs. *how*
