+### Output
+
+The main output of gomu gomu is the report output location specified in specified in the configuration file.
+
+At the end of all benchmarks gomu gomu will collect the results into a single json file with the following structure:
+
+- `users`: The amount of goose users used to do the benchmarks, changed by `concurrency`
+
+- `all_bench_report`: A report over all benchmarks done, has a portion of metrics that `benches` has
+
+- `benches`: A array of reports for all benchmarks
+
+  - `name`: The name of the benchmark
+  - `amount`: How many times this benchmark was ran
+  - `metrics`: Metrics over the whole benchmark
+
+    - `name`: The name of the metric
+    - `unit`: The unit of the metric, empty when there is no unit
+    - `value`: The metrics value, a number
+
+      - For floats, `Infinite` and `NaN` are not JSON numbers and thus will be turned into `null`
+      - Values gotten from submission time are calculated from the latency to add a new transaction to the node
+      - Values gotten from verification time are calculated from the latency to get the transaction receipt after the transactions have been processed
+
+  - `last_x_blocks_metrics`: Metrics over the last blocks of the benchmark
+
+    - `num_blocks`: The amount of last transactions that were measured
+    - `metrics`: An array of metrics
+
+- `extra`: Extra information for this run
+
+Gomu gomu will also display into the console information about each step in the benchmark.
