-todo how to exclude shaded protobuf classes
+You can exclude the shaded otel classes including the
+`prometheus-metrics-exporter-opentelemetry-no-otel` module and excluding the
+`prometheus-metrics-exporter-opentelemetry` module in your build file.
+
+For example, in Maven:
+
+```xml
+<dependencies>
+  <dependency>
+      <groupId>io.prometheus</groupId>
+      <artifactId>prometheus-metrics-exporter-opentelemetry</artifactId>
