Overview

Imports card data from a local or remote deck

The cards' content for the import is stored for every card in a separate file, other attributes like name or type are stored for all cards together in a yml file.

To update a card's content you only have to change the card's content file. The merge method will recognize that the file was changed since the last merge and merge it into the cards table To update other attributes change them in the yml file and either remove the 'merged' value or touch the corresponding content file
