-## Aligned aggregation mode
+# Aligned aggregation mode
 
+## How to run it locally
+
+1. Deploy aligned contracts on anvil:
+```shell
+make deploy_aligned_contracts
+```
+
+2. Start anvil:
+```shell
+make anvil_start_with_block_time
+```
+
+2. Compile and run aggregator (this might take long as it uses more aggressive optimization leves):
+```shell 
+cd aggregation-mode
+# This will compile with a mock prover
+cargo run --release
+# This will run the prover (requires powerful machine)
+cargo build --release --features prove
+```
