+Benchmarking
+============
+
+To build all of the benchmarks:
+```
+# Run from benchmark directory
+cd benchmark
+mvn clean install
+```
+
+Set `GOOGLE_APPLICATION_CREDENTIALS`:
+```
+export GOOGLE_APPLICATION_CREDENTIALS=path/to/service_account.json
+```
+
+To run a benchmark jar, run the following command
+```
