Installed. Now:
  1. Edit $TARGET/.env : database, APP_URL (https), DMS_ADMIN_EMAIL, DMS_ADMIN_PASSWORD, SITE_*, MPESA_*, ETIMS_*
  2. Create the database and user, then:     cd $TARGET && php artisan migrate --force --seed
  3. Change the sample branches (HQ, NBO, MSA) to your real ones under Branches, and sign in as the admin you set in .env
  4. Web server:      deploy/nginx.conf        (point the root at $TARGET/public, add HTTPS)
  5. Queue worker:    deploy/supervisor-dms-worker.conf
  6. Scheduler cron:  deploy/crontab.txt
  7. Optimise:        php artisan config:cache && php artisan route:cache && php artisan view:cache && php artisan event:cache
  8. Check:           php artisan dms:preflight      (and again with --live before real customers)
