+
+This Scheduler will run once every minute unlike the Heroku scheduler which only runs every 10 mintues.
+
+To use this scheduler with Laravel 5.4+ add this file to /app/Console/Commands/RunScheduler.php
+Register this file in app/Console/Kernel.php
+
+protected $commands = [
+...
+Commands\RunScheduler::class
+...
+]
+
+Add this line to your Procfile:
+
+scheduler: php -d memory_limit=512M artisan schedule:cron
+
+Push to Heroku and you will see you have a new dyno option called Scheduler, start ONE only.
+
+I highly recommend using Artisan::queue to run your cron jobs so that your scheduler does not over run.
