+## Requirements
+
+- Android 6.0 (API level 23) or later: the SDK's `minSdk` is 23.
+- `compileSdk` 34 or later and Android Gradle Plugin 8.1.1 or later, as required by the SDK's AndroidX dependencies.
+- JDK 17 or later to build your app: the SDK is compiled to Java 17 bytecode.
+- Kotlin apps: Kotlin 2.0 or later, since the SDK's dependencies bring in `kotlin-stdlib` 2.1.
+- The `android.permission.INTERNET` permission in your app's `AndroidManifest.xml`. The SDK doesn't declare it, so
+  your app must:
+
+```xml
+<uses-permission android:name="android.permission.INTERNET" />
+```
+
 ## Installing
 
 This SDK is published using [JitPack](https://jitpack.io/), so you need to add the repository to your application build.
-Add the following in your root `build.gradle` at the end of `repositories`:
+Add it to the `dependencyResolutionManagement` block of your `settings.gradle`:
+
+```groovy
+dependencyResolutionManagement {
+    repositories {
+        google()
+        mavenCentral()
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+
+Or, in `settings.gradle.kts`:
 
 ```kotlin
-allprojects {
+dependencyResolutionManagement {
     repositories {
-        ...
-        maven {
-            url 'https://jitpack.io'
-        }
+        google()
+        mavenCentral()
+        maven("https://jitpack.io")
     }
 }
 ```
 
+Projects that still declare repositories in the root `build.gradle` can add the same `maven` line to
+`allprojects { repositories { ... } }` instead.
+
 Then add the dependency to the SDK in your app `build.gradle`:
 
+```groovy
+dependencies {
+    implementation 'com.github.Optable:optable-android-sdk:v1.2.0'
+}
+```
+
+Or, in `build.gradle.kts`:
+
 ```kotlin
 dependencies {
-    implementation 'com.github.Optable:optable-android-sdk:VERSION_TAG'
+    implementation("com.github.Optable:optable-android-sdk:v1.2.0")
 }
 ```
 
-Replace `VERSION_TAG` with the latest or desired [SDK release](https://github.com/Optable/optable-android-sdk/releases).
+Replace `v1.2.0` with the latest or desired [SDK release](https://github.com/Optable/optable-android-sdk/releases).

 ### Building
 
 To build the Kotlin demo app, from [Android Studio](https://developer.android.com/studio), navigate to `File > Open` and
 open the `DemoApp/DemoAppKotlin` directory. To build the Java demo app, open the `DemoApp/DemoAppJava` directory. In
-both cases, you should be able to build and run the resulting project directly, since it will automatically download the
-`co.optable.android_sdk` library from the [JitPack](https://jitpack.io/) Maven repository.

+from the source in this repository (`useReleaseSdk=false` in the demo's `gradle.properties`). Set `useReleaseSdk=true` to
