# The MarlinFirmware/Configurations layout could be broken up into branches,
# but this makes management more complicated and requires more commits to
# perform the same operation, so this uses a single branch with subfolders.
#
# init - Initialize the repo with a base commit and changes:
#   - Source will be an 'import' branch containing all current configs.
#   - Create an empty 'BASE' branch from 'init-repo'.
#   - Add Marlin config files, but reset all to defaults.
#   - Commit this so changes will be clear in following commits.
#   - Add changed Marlin config files and commit.
#
# manual - Manually import changes from the Marlin repo
#   - Replace 'default' configs with those from the Marlin repo.
#   - Wait for manual propagation to the rest of the configs.
#   - Run init with the given 'source' and 'dest'
