+#### Adding a new benchmark
+To add additional benchmarks that should run for every PR go to `.gitlab/scripts/run-benchmarks.sh`.
+Add the name of your benchmark to the list in `-bench "BenchmarkConcurrentTracing|BenchmarkStartSpan"` using pipe character separators. Note that your new benchmark must already exist in the `main` branch, for that reason it is best for new benchmarks to be added in their own PR and a second PR opened afterwards to add them to the PR benchmark script.
