 ### Tracing
 
-HLS records opentelemetry eventlog traces via [opentelemetry](https://hackage.haskell.org/package/opentelemetry). To generate the traces, build with `-eventlog` and run with `+RTS -l`. To visualize the traces, install [Tracy](https://github.com/wolfpld/tracy) and use [eventlog-to-tracy](https://hackage.haskell.org/package/opentelemetry-extra) to open the generated eventlog.
