 ## Next Steps
 The next step is to read the paper [Narwhal and Tusk: A DAG-based Mempool and Efficient BFT Consensus](https://arxiv.org/pdf/2105.11827.pdf). It is then recommended to have a look at the README files of the [worker](https://github.com/facebookresearch/narwhal/tree/master/worker) and [primary](https://github.com/facebookresearch/narwhal/tree/master/primary) crates. An additional resource to better understand the Tusk consensus protocol is the paper [All You Need is DAG](https://arxiv.org/abs/2102.08325) as it describes a similar protocol. 
 
-The [benchmark folder](https://github.com/facebookresearch/narwhal/tree/master/benchmark) explains how to benchmark the codebase and read benchmarks' results. It also provides a step-by-step tutorial to run benchmarks on [Amazon Web Services (AWS)](https://aws.amazon.com) accross multiple data centers (WAN).
