+## Benchmark Requirements
+
+The benchmarks are run using [asv][1] which is also their only requirement.
+
+## Running the benchmarks
+
+To run the benchmarks, call `asv run --python=same`. You cannot use the
+plain `asv run` command at the moment as asv cannot handle python packages
+in subdirectories of a repository.
