 We have two types of benchmarking:
 
-- E2E benchmarking running the service (HTTP or UDP tracker).
+- E2E benchmarking running the UDP tracker.
 - Internal torrents repository benchmarking.
 
 ## E2E benchmarking
 
 We are using the scripts provided by [aquatic](https://github.com/greatest-ape/aquatic).
 
-Installing both commands:
+How to install both commands:
 
 ```console
-cargo install aquatic_udp_load_test
-cargo install aquatic_http_load_test
+cargo install aquatic_udp_load_test && cargo install aquatic_http_load_test
+```
+
+You can also clone and build the repos. It's the way used for the results shown
+in this documentation.
+
+```console
+git clone [email protected]:greatest-ape/aquatic.git
+cd aquatic
+cargo build --release -p aquatic_udp_load_test
