+# Usage {#usage}
+
+This chapter describes usage of the package. That includes creating tenants, deleting tenants, storing data in the tenant storage.
+
+Most pages will use the `tenancy()` helper function. This package comes with two helpers - `tenancy()` and `tenant()`. They do the same thing, so you can use the one that reads better given its context.
+
+`tenant()->create()` reads better than `tenancy()->create()`, but `tenancy()->init()` reads better than `tenant()->init()`.
+
+You can pass an argument to the helper function to get a value out of the tenant storage. `tenant('plan')` is identical to [`tenant()->get('plan')`]({{ $page->link('tenant-storage') }}).
+
+The package also comes with two facades. `Tenancy` and `Tenant`. Use what feels the best.
+
+Both the helpers and the facades resolve the `TenantManager` from the service container.
