-## Requirements 
-- [Android Plugin for Gradle 7.4.2](https://developer.android.com/studio/releases/gradle-plugin#7.4.2)
-- [Kotlin 1.5.20](https://blog.jetbrains.com/kotlin/2021/06/kotlin-1-5-20-released/)
+# Overview
+ArcGIS Maps SDK Kotlin for Android v200.0.0 samples.  The `main` branch of this repository contains sample app modules for the latest available version of the [ArcGIS Maps SDK Android Kotlin](https://developers.arcgis.com/android/). Samples released under older versions can be found through the [git tags](https://github.com/Esri/arcgis-maps-sdk-kotlin-samples/tags).  Please read our [wiki](https://github.com/Esri/arcgis-maps-sdk-kotlin-samples/wiki) for help with working with this repository.
 
-## Import Kotlin Samples into Android Studio
+# Prerequisites
+* The samples are building with `compileSdkVersion 33`
+* [Android Studio](http://developer.android.com/sdk/index.html)
+* [An ArcGIS Developers API key](https://developers.arcgis.com/android/get-started/#3-get-an-api-key)
 
-- From the Android Studio toolbar select **File > Import Project** project from the **Welcome Quick Start**.
-- Navigate to the **kotlin** project directory and click OK
+## Developer Instructions
+Please read our [developer instructions wiki page](https://github.com/Esri/arcgis-maps-sdk-kotlin-samples/wiki/dev-instructions) to set up your developer environment with Android Studio.  Instructions include forking and cloning the repository for those new to Git.
+
+Once the project is cloned to disk you can import into Android Studio:
+
+* From the Welcome to Android Studio screen, click the **Open** button. (If you're already inside a project, click **File > Open** in the menu bar instead.)
+* Navigate to the **arcgis-maps-sdk-kotlin-samples/** folder and click **OK**.
+
+## Accessing Esri location services
+Accessing Esri location services, including basemaps, routing, and geocoding, requires authentication using either an API Key or an ArcGIS identity:
+ 1. API key: A permanent key that gives your application access to Esri location services. Visit your [ArcGIS Developers Dashboard](https://developers.arcgis.com/dashboard) to create a new API key or access an existing API key.
+ 
+The Android samples in this repository have been structured to use an API key, set once, which will run in all samples. Set your API key in the `gradle.properties` file located in the `/.gradle` folder within your home directory (`/Users/<user_name>/.gradle/gradle.properties`). The API_KEY property should contain quotes around the key itself: `API_KEY = "YOUR_API_KEY"`
+
+2. ArcGIS identity: An ArcGIS named user account that is a member of an organization in ArcGIS Online or ArcGIS Enterprise.
+
+## Run a sample
+Once you have set up your developer environment you can run any sample from within Android Studio by selecting the app module from the **Edit Configurations** drop down and clicking the **Run** button from the toolbar. 
+
+### Build/Run sample from Gradle
+You can execute all the build tasks using the [Gradle Wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html) command line tool. It's available as a batch file for Windows (gradlew.bat) and a shell script for Linux/Mac (gradlew.sh) and it is accessible from the root of the project.  
+
+- Build a debug APK
+
+```
+$ ./gradlew assembleDebug
+```
+
+- Run the app
+
+**Device**
+```
+adb -d install path/to/sample.apk
+```
+
+Built APK's are saved to **arcgis-maps-sdk-kotlin-samples/[module-name]/build/outputs/apk/**. More information about running apps on devices can be found [here](https://developer.android.com/studio/run/device.html).
+
+### Run samples through the sample viewer
+The samples in this repository can also be viewed in a single sample viewer app. It can be found on the Play Store or [on ArcGIS Online](https://arcgisruntime.maps.arcgis.com/home/item.html?id=21ac248ea189406c821400dc28bf686c). If downloading from ArcGIS Online, follow these instructions to run the app locally on your device:
+- Download and unzip the file to get the apk **ArcGIS_Runtime_Sample_Viewer_Android_20000.apk**.
