+## Variables
+
+The following nginx variables are set by OpenTelemetry:
+
+- `opentelemetry_context_traceparent` - [W3C trace
context](https://www.w3.org/TR/trace-context/#trace-context-http-headers-format),
e.g.: `00-0af7651916cd43dd8448eb211c80319c-b9c7c989f97918e1-01`
+- `opentelemetry_trace_id` - Trace Id of the current span
+- `opentelemetry_span_id` - Span Id of the current span
+
+How to use variables? you have to add it to your configuration file
(`conf/config.yaml`):
+
+```yaml title="./conf/config.yaml"
+ nginx_config:
+ http_server_configuration_snippet: |
+ set $opentelemetry_context_traceparent ""
