+
+## Getting Started
+
+### Bench on Testnet
+
+1. Assume the owner privkey is `af44a4755acccdd932561db5163d5c2ac025faa00877719c78bb0b5d61da8c94`. Make sure this address has enough capacity.
+
+2. Generate 9000 users, dispatch them 1 cells per user, 7100000000 capacity per cell.
+
+  ```shell
+  CKB_BENCH_OWNER_PRIVKEY=af44a4755acccdd932561db5163d5c2ac025faa00877719c78bb0b5d61da8c94 \
+  ./target/release/ckb-bench dispatch \
+    --data-dir data/ \
+    --rpc-urls http://127.0.0.1:8111 \
+    --capacity-per-cell 7100000000 \
+    --cells-per-user 1 \
+    --n-users 9000
+  ```
+
+3. Bench 300 seconds, benched transactions type are 2-in-2-out, sending transaction interval is 10ms
+
+  ```shell
+  CKB_BENCH_OWNER_PRIVKEY=af44a4755acccdd932561db5163d5c2ac025faa00877719c78bb0b5d61da8c94 \
+  ./target/release/ckb-bench bench \
+    --is-smoking-test \
+    --data-dir data/ \
+    --rpc-urls http://127.0.0.1:8111 \
+    --bench-time-ms 300000 \
+    --n-users 9000 \
+    --n-inout 2 \
+    --tx-interval-ms 10
+  ```
+
+2. Cleanup. Collect cells back to owner.
+
+  ```shell
+  CKB_BENCH_OWNER_PRIVKEY=af44a4755acccdd932561db5163d5c2ac025faa00877719c78bb0b5d61da8c94 \
+  ./target/release/ckb-bench collect \
+    --data-dir data/ \
+    --rpc-urls http://127.0.0.1:8111 \
+    --n-users 9000
+  ```
