+pg_clickhouse ClickBench
+========================
+
+This ClickBench configuration benchmarks [pg_clickhouse] running inside
+PostgreSQL and pushing queries down to a ClickHouse database. Files:
+
+*   `benchmark.sh`: Runs the benchmark
+*   `clickhouse.sh`: Installs ClickHouse and loads it with data; based on the
+    [ClickHouse benchmark script](../clickhouse/benchmark.sh)
+*   `create-postgres.sql`: Loads pg_clickhouse into Postgres and creates the
+    foreign table
+*   `create-tuned-memory.sql`, `create-tuned.sql`, and `create.sql`: Scripts
+    that create the ClickHouse table, copied from the [ClickHouse
+    Config](../clickhouse/)
+*   `postgres.sh`: Installs, configures, and starts PostgreSQL; based on the
+    [PostgreSQL benchmark script](../postgresql/benchmark.sh)
+*   `queries.sql`: The benchmark queries, identical to the [PostgreSQL
+    queries](../postgresql/queries.sql)
+*   `README.md`: This file
+*   `run.sh`: Runs the benchmark; identical too the [PostgreSQL run
+    script](../postgresql/run.sh)
+*   `template.json`: Describes this benchmark configuration
+
+## Environment Variables
+
+### TOTAL_PARTITIONS
+
+Set `$TOTAL_PARTITIONS` to the number of partitions to load into ClickHouse.
+Defaults to 100.
+
+### EXPLAIN
+
+Set `$EXPLAIN` to a true value to run each query with
+`EXPLAIN (ANALYZE VERBOSE)`.
