-# Receivers
-
-The `Receiver` API defines a webhook receiver that triggers
-a synchronization for a group of sources.
-
-## Specification
-
-```go
-type ReceiverSpec struct {
-	// Type of webhook sender, used to determine
-	// the validation procedure and payload deserialization.
-	// +kubebuilder:validation:Enum=github;gitlab
-	// +required
-	Type string `json:"type"`
-
-	// A list of sources to be notified about changes.
-	// +required
-	Sources []corev1.TypedLocalObjectReference `json:"sources"`
-}
-```
-
-Webhook sender type:
-
-```go
-const (
-	GitHubWebhook string = "github"
-	GitLabWebhook string = "gitlab"
-)
-```
-
-## Status
-
-```go
-type ReceiverStatus struct {
-	// Generated webhook URL in the format
-	// of '/hook/sha256sum(token)'.
-	// +required
-	URL string `json:"url"`
-
-	// Generate token used to validate the payload authenticity.
-	// +required
-	Token string `json:"token"`
-}
-```
-
-## Implementation
-
-The source controller handles the webhook requests on a dedicated port. This port can be used to create
-a Kubernetes LoadBalancer Service or Ingress to expose the receiver endpoint outside the cluster.
-
-When a `Receiver` is created, the controller generates a random token and
-sets the `Receiver` status token and URL in the format `/hook/sha256sum(token)`.
-The `ReceiverReconciler` creates an indexer for the SHA265 digest
-so that it can be used as a field selector.
-
-When source controller receives a POST request:
-* extract the SHA265 digest from the URL
-* loads the `Receiver` using the digest field selector
-* extracts the signature from HTTP headers based on `spec.type`
-* validates the signature using `status.Token` based on `spec.type`
-* extract the event type from the payload 
-* triggers a synchronization for `spec.sources` if the event type is `push`
