+### Requesting a proof in an aggregated manner
+
+For some circuits it makes sense to request proofs in an aggregated manner. 
+More on this can be found in the [zkLLVM hints on circuits writing](https://docs.nil.foundation/zkllvm).
+
+To request a proof in an aggregated manner, you need to use slightly different command:
+
+```bash
+python3 aggregated_request.py --cost <cost of the request> --input <json file with public_input> --statement-key <key of the statement> --aggregation-ratio 4
+```

 ## 4. Awaiting for Proposals
 
 Here the proof requester waits for matching engine to either match an existing order or wait for proposals to be submitted against this circuit/statement.
