+# dioxus-cli-config
 
-The **dioxus-cli-config** contains the configuration for the **dioxus-cli**.
+A crate that provides key/value names and types for configuring Dioxus applications at runtime.
+
+This crate exists for us to very cleanly define the exact fields we want to pass down to Dioxus applications at runtime but without exposing the entire config object.
+
+This leads to faster compile times, smaller binaries, and a clearer distinction between the config and the application.
