errors in drush command help

I cannot find any documentation on drupal.org on how to use this module. Is there any? If yes, can you link to it from the project page?

There are some drush commands but the explanation isnt very clear:

The help text for the cdi1 command is:

Write back configuration to module's config/install directory.
List which configuration settings you want to export in the
module's info file by listing them under 'config_devel', as shown below:

For cde the help text is:

Write back configuration to module's config/install directory.
List which configuration settings you want to export in the
module's info file by listing them under 'config_devel', as shown below:

There is probably a mistake there.

Also there seems to be confusion about cdi vs cdi1 command ...

If there is no documentation yet, can you provide some basics?
