-Exporting Traces
 
 To export collected tracing data, register at least one exporter. You can use
 one of the provided exporters or write your own.
 
-    trace.RegisterExporter(exporter)
+	trace.RegisterExporter(exporter)
 
 By default, traces will be sampled relatively rarely. To change the sampling
 frequency for your entire program, call ApplyConfig. Use a ProbabilitySampler
 to sample a subset of traces, or use AlwaysSample to collect a trace on every run:
 
-    trace.ApplyConfig(trace.Config{DefaultSampler: trace.AlwaysSample()})
+	trace.ApplyConfig(trace.Config{DefaultSampler: trace.AlwaysSample()})
 
 Be careful about using trace.AlwaysSample in a production application with
 significant traffic: a new trace will be started and exported for every request.
