### Changes
Below settings were tested in Kotlin DSL based Android Projects

1. ``` repositories {
maven(url = "https://storage.googleapis.com/download.flutter.io")
maven(url =
"/Users/shivam/StudioProjects/flutter_module/build/host/outputs/repo")
    }```
 need to be added in `settings.gradle.kts`

ADDED
2. Implementing `profileImplementation` in Kotlin DSL projects

~~**Note**: I still cannot find about `profileImplementation` in DSL.
will find and update soon.~~

+### Kotlin DSL based Android Project
+
+After an `aar` build of a Kotlin DSL-based Android project,
+follow these steps to add the flutter_module.
+
+Include the flutter module as a dependency in 
+the Android project's `app/build.gradle` file.
+<?code-excerpt title="MyApp/app/build.gradle.kts"?>
+```gradle
+android {
+    buildTypes {
+        release {
+          ...
+        }
+        debug {
+          ...
+        }
+        create("profile") {
+            initWith(getByName("debug"))
+        }
+}
+dependencies {
+  // ...
+  debugImplementation "com.example.flutter_module:flutter_debug:1.0"
+  releaseImplementation 'com.example.flutter_module:flutter_release:1.0'
+  add("profileImplementation", "com.example.flutter_module:flutter_profile:1.0")
+}
+```
+
+The `profileImplementation` ID is a custom `configuration` to be
+implemented in the `app/build.gradle` file of a host project.
+
+<?code-excerpt title="host-project/app/build.gradle.kts"?>
+```gradle
+configurations {
+    getByName("profileImplementation") {
+    }
+}
+```
+
+<?code-excerpt title="MyApp/settings.gradle.kts"?>
+```gradle
+include(":app")
+
+dependencyResolutionManagement {
+    repositories {
+        maven(url = "https://storage.googleapis.com/download.flutter.io")
+        maven(url = "some/path/flutter_module_project/build/host/outputs/repo")
+    }
+}
 ```
