+Example with Debug level (similar funcs exist for the other levels). Log on zap only:
 
-```
+```go
 func Debug(log string, fields ...zapcore.Field)
 ```
 
 Log on Zap and on Opentracing. The span is given directly or is retrieved from the context:
 
-```
+```go
 func DebugWithSpan(span opentracing.Span, log string, fields ...zapcore.Field)
 func DebugWithContext(ctx context.Context, log string, fields ...zapcore.Field)
 ```
