+## Continuous Benchmarking
+
+We use the [CodSpeed](https://codspeed.io) service to continuously track PyGMT's
+performance. The `pytest-codspeed` plugin collects benchmark data and uploads it to the
+CodSpeed server, where results are available at <https://codspeed.io/GenericMappingTools/pygmt>.
+
+Benchmarking is handled through the `benchmarks.yml` GitHub Actions workflow. It's
+automatically executed when a pull request is merged into the main branch. To trigger
+benchmarking in a pull request, add the `run/benchmark` label to the pull request.
+
+To include a new test in the benchmark suite, apply the `@pytest.mark.benchmark`
+decorator to a test function.
