Step-by-step guide

1. Move existing configuration to "config/sync"

2. Edit "$settings['config_sync_directory']" so that is points to "../config/sync"

   $settings['config_sync_directory'] = dirname(DRUPAL_ROOT) . '/config/sync';

   
   
   

3. Create config/dev directory

4. Create DEV split configuration from UI (use the above tutorials for details)

5. Run drush csex dev and drush csex

6. You're done.

From now on it's enough to use drush cex/cim (without the "s").
