Background Drupal 10 Upkeep and Help Service  I actually didn’t know what I used to be doing, however on a neighborhood Home windows Hyper-V digital machine, I put in a Drupal 10 8 website utilizing Bitnami, then put in one other website utilizing composer. Then I used composer to put in drush.  All that appeared to work.  (Thus C Drupal 10 Upkeep and Help ServiceBitnamiDrupal 108 has composer and drush put in, and a Drupal 10 8 website at ..appsDrupal 10htdocs  and C Drupal 10 Upkeep and Help ServiceDrupal 108 has composer and drush put in and ..net has a Drupal 10 8 website)  I feel this may let me develop in Drupal Development Company C Drupal 10 Upkeep and Help Service8 folder, then use composer to INSTALL my modifications in Drupal Development Company bitnami folder, and ultimately transfer all of it from Drupal Development Company native machine to Drupal Development Company net.
