+The `middleware` should be put as early as possible, since only logs after this middleware will get the tracing data. The middleware will lookup the active project ID from GCP. Alternatively, you can set the `GCP_PROJECT` environment variable for this purpose.
+
+Use the `getHttpTraceHeader` function to pass tracing headers to downstream services.
+
+If you want to decorate logs with custom data, use the exported `decorateLogs` function. In order to use this, the middleware needs to be installed first.
