+## Utilities
+### Copying Project Dependencies
+Sometimes you need to depend on a specific configuration of a project. This is
+annoying to do with Kotlin build scripts as you have to copy the dependency then
+change the configuration. 
+
+To make this easier, the plugin provides a utility function that allows you to quickly
+copy a dependency and change the configuration:
+```kotlin
+import co.hinge.gradle.projectaccessors.copy
+
+dependencies {
+    implementation(projects.someModule.copy(targetConfiguration = "someConfiguration"))
+}
+```

 ## Supported Gradle Versions
 The plugin is tested with all minor Gradle versions from 7.6 up to 8.7, but may work with other versions.
