From now on you're on your own. The rest of this README has not been checked and things may or may not work (although they should).
Defining Subscription Plans
Subscription plans may be defined in your app/Providers/SparkServiceProvider.php file. This file contains a customizeSubscriptionPlans method. Within this method, you may define all of your application's subscription plans. There are a few examples in the method to get you started.
When defining a Spark plan, the plan method accepts two arguments: the name of the plan and the Stripe ID of the plan. Be sure that the Stripe ID given to the plan method corresponds to a plan ID on your Stripe account:
Once teams are enabled, a team name will be required during registration, and a Teams tab will be available in the user settings dashboard.
Team roles may be defined in the customizeRoles method of the SparkServiceProvider.
Customizing Spark Views
You may publish Spark's common Blade views by using the vendor:publish command:
php artisan vendor:publish --tag=spark-basics
All published views will be placed in resources/views/vendor/spark.
If you would like to publish every Spark view, you may use the spark-full tag:
php artisan vendor:publish --tag=spark-full
You are free to change any of these require statements to load your own Vue component for a given screen. Most likely, you will want to copy the original component as a starting point for your customization.
