 # If a configpath has spaces (or quotes) escape them or enquote the path
+# If no branch: prefix is given use configs based on the current branch name.
+# e.g., For `latest-2.1.x` name the working branch something like "my_work-2.1.x."
+#       The branch or tag must first exist at MarlinFirmware/Configurations.
+#       The fallback branch is bugfix-2.1.x.
