I'm setting up my first BackdropCMS website on a hetzner.de managed server (webhosting Level 9).
After having succesfully installed composer
$ composer --version
Composer version 2.0.8 2020-12-03 17:20:38
I issued the command
$ composer global require drush/drush:dev-master
which installed drush into .config/composer/vendor/drush:
$ drush version
Drush version : 10.3.2-dev
After typing drush I get an error at the bottom of the list with available commands:
! [NOTE] Drupal root not found. Pass --root or a @siteAlias in order to see
! Drupal-specific commands.
I am probably overseeing something very basic, but it's not clear to me how to proceed from here to start a fresh backdrop website project from here.
Once I have this fully figured out, I plan to write a HOWTO for Hetzner clients.
