 ### Profiling PRs
 
-During development, you need to add automated tests where possible. There are a few `make test*` targets that you can use to execute your unit or integration tests. If your contribution requires profiling to check memory and/or CPU usage, you can use `--cpuprofile` and/or `--memprofile` global cli flags to collect runtime profiling data for analysis.
