+## Build and publish to local Maven repository
+```shell
+source uniffi_bindgen_generate_kotlin.sh
+./gradlew publishToMavenLocal
+```
+
+## How to Use
+To use the Kotlin language bindings for [`ldk-node`] in your JVM project, add the following to your gradle dependencies:
+```kotlin
+repositories {
+    mavenCentral()
+}
+
+dependencies {
+    implementation("org.ldk:ldk-node:0.0.1")
+}
+```
+
+You may then import and use the `org.ldk_node` library in your Kotlin code. For example:
+```kotlin
+import uniffi.ldk_node.Builder
+import uniffi.ldk_node.Node
+
+fun main() {
+    val node: Node = Builder().build()
+}
+```
