 # Network builder
 
-To build a network or a node, you first need to create a [`CoreBuilder`] object using the [`CoreBuilder::with_config`] method to create a bootstrap node, then you can simply call [`CoreBuilder::build`] to set up the network. This will create a [`Core`] struct with methods you can use to send and receive data to/from the network.
+To build a network or a node, you first need to create a [`CoreBuilder`] object using the [`CoreBuilder::with_config`] method to create a bootstrap node, then you can simply call [`CoreBuilder::build`] to set up the network. This will create a [`Core`] struct which serves as the interface between an application and the network. It contains several methods used to interact and perform activities on the network.
 
 The [`CoreBuilder::with_config`] method takes a parameter - [`BootstrapConfig`], to pass in a node's bootstrap configuration.
