+# Errors
+
+The standardizing of errors to be used in Dapr based on the gRPC Richer Error Model and [accepted dapr/proposal](https://github.com/dapr/proposals/blob/main/0009-BCIRS-error-handling-codes.md).
+
+## Usage
+
+Define the error
+```go
+import kitErrors "github.com/dapr/kit/errors"
+
+// Define error in dapr pkg/api/<building_block>_errors.go
+func PubSubNotFound(name string, pubsubType string, metadata map[string]string) error {
+	message := fmt.Sprintf("pubsub %s is not found", name)
+
+	return kitErrors.NewBuilder(
+		grpcCodes.NotFound,
+		http.StatusBadRequest,
+		message,
+		kitErrors.CodePrefixPubSub+kitErrors.CodeNotFound,
+	).
+		WithErrorInfo(kitErrors.CodePrefixPubSub+kitErrors.CodeNotFound, metadata).
+		WithResourceInfo(pubsubType, name, "", message).
+		Build()
+}
+```
+
+Use the error
+```go
+import apiErrors "github.com/dapr/dapr/pkg/api/errors"
+
+// Use error in dapr and pass in relevant information
+err = apiErrors.PubSubNotFound(pubsubName, pubsubType, metadata)
+
+```
