 # sui-swarm
 
 This crate contains a collection of utilities for managing complete Sui
-Networks. The intended use for these utilities is for performing end-to-end
-testing and benchmarking. In the future the expectation is that we'll have
+networks. The intended use for these utilities is for performing end-to-end
+testing and benchmarking. In the future, the expectation is that we'll have
 support for a number of different "backends" for how the network is operated.
-Today the only supplied backed is the `memory` backend, although in the future
-we should be able to support a multi-process and even a k8s backend.

 ## Backends
 
 ### memory
 
 An `in-memory`, or rather `in-process`, backend for building and managing Sui
-Networks that all run inside the same process. Nodes are isolated from one
+networks that all run inside the same process. Nodes are isolated from one
 another by each being run on their own separate thread within their own `tokio`
 runtime. This enables the ability to properly shut down a single node and
 ensure that all of its running tasks are also shut down, something that is
