+# Automatic Trace/Span ID Extraction
+
+You can automatically populate the Trace, SpanID, and TraceSampled fields of an Entry object by providing an [http.Request] object
+within the Entry's HTTPRequest field:
+
+	logging.Entry{
+		HTTPRequest: &logging.HTTPRequest{
+			Request: // Reference to your http.Request here
+		}
+	}
+
+When Entry with an [http.Request] is logged, its Trace, SpanID, and TraceSampled fields may be automatically populated as follows:
+
+ 1. If you are instrumenting your application with [OpenTelemetry], more specifically [otelhttp],
+    the Entry's Trace, SpanID, and TraceSampled will be populated with information from the [http.Request]'s span context.
+ 2. Trace, SpanID, and TraceSampled fields will be populated from information from the http.Request's [W3C Traceparent]
+    or [X-Cloud-Trace-Context] headers, if those headers exist.
+
+Note that if Trace, SpanID, or TraceSampled are explicitly provided within an Entry object, then those values take precedence over values automatically
+extracted values.
