+## ✨ Features
+
+- The Kotlin client is compatible with Kotlin `1.6` and higher.
+- It is compatible with Kotlin project on the JVM, such as backend and Android applications.
+- It relies on the open source Kotlin libraries for seamless integration into Kotlin projects:
+    - [Kotlin multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html).
+    - [Kotlinx serialization](https://github.com/Kotlin/kotlinx.serialization) for json parsing.
+    - [Kotlinx coroutines](https://github.com/Kotlin/kotlinx.coroutines) for asynchronous operations.
+    - [Ktor](https://github.com/ktorio/ktor) HTTP client.
+- The Kotlin client integrates the actual Algolia documentation in each source file: Request parameters, response fields, methods and concepts; all are documented and link to the corresponding url of the Algolia doc website.
+- The client is thread-safe. You can use `SearchClient`, `AnalyticsClient`, and `InsightsClient` in a multithreaded environment.
+
+## 💡 Getting Started
+
+Install the Kotlin client by adding the following dependency to your `gradle.build` file:
+
+  ```gradle
+  repositories {
+     mavenCentral()
+  }
+
+  dependencies {
+     implementation "com.algolia:algoliasearch-client-kotlin:$version"
+  }
+  ```
+Also, choose and add to your dependencies one of [Ktor http client engines](https://ktor.io/docs/http-client-engines.html).
+Alternatively, you can use [algoliasearch-client-kotlin-bom](/client-bom).  
+For full documentation, visit the **[Algolia Kotlin API Client](https://www.algolia.com/doc/api-client/getting-started/install/kotlin/)**.
+
+### Guides

+- [DSL](https://github.com/algolia/algoliasearch-client-kotlin/tree/master/docs/DSL.md)
+- [Serialization](https://github.com/algolia/algoliasearch-client-kotlin/tree/master/docs/Serialization.md)
