+NOTES
+=====
+
+The `bootstrap` command in `drupal-init-tools` uses `drush` for the site
+installation, and `drush` requires MySQL super-user access to create new MySQL
+users and databases.
+
+On some Linux distributions, like Debian, the MariaDB server is configured by
+default to only allow access to the `root` user via the `unix_socket` plugin,
+making it unusable by `drush`. In these cases it's recommended to create e new
+MySQL super-user.
+
+For password-less access create a MySQL admin user correspondent to the system
+user which will excute `drush` (e.g. the current user):
+
+::
+
+  sudo /usr/bin/mysql -e "GRANT ALL ON *.* TO '$USER'@'localhost' IDENTIFIED VIA unix_socket WITH GRANT OPTION"
+
+
+For password regulated access create a user with a password:
+
+::
+
+  sudo /usr/bin/mysql -e "GRANT ALL ON *.* TO 'USERNAME'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION"
+
+
+For details see also the **PASSWORDS** section in the README.Debian file
+provided by the mariadb-server Debian package, either in
+`/usr/share/doc/mariadb-server-10.1/README.Debian.gz` or at 
+https://salsa.debian.org/mariadb-team/mariadb-10.1/blob/stretch/debian/mariadb-server-10.1.README.Debian#L73
+
+The settings in the `bootstrap.conf` file have to be adjusted according to how
+super-user access has been configured.
