To install Zetteldeft for spacemacs, simply add the Deft layer to your .spacemacs file and enable zetteldeft support.

Locate dotspacemacs-configuration-layers in your .spacemacs and add the variables as suggested below.

(setq-default dotspacemacs-configuration-layers
  '((deft :variables deft-zetteldeft t)))
