[Layer 1: Domain events](/docs/layer-1/)

This chapter adds your domain events. A [CloudEventConverter](/docs/layer-1/cloudevent-conversion/) maps them to CloudEvents and back, and every part in this section uses it, so your code reads and writes domain events while the event store keeps CloudEvents. Most applications should start here.
