@@ -35,3 +35,51 @@ Most of complex modules are built with next hierarchy:
     * `common` part contains routes which are common for clients and servers
     * `client` submodule contains clients which are usually using `UnifiedRequester` to make requests using routes from `ktor/common` module and some internal logic of requests
     * `server` submodule (in most cases `JVM`-only) contains some extensions for `Route` instances which usually will give opportunity to proxy internet requests from `ktor/client` realization to some proxy object

+## Gradle Templates
+
+All templates can be used by applying them in your project's build.gradle files using the `apply from` directive. For example:
+
+```gradle
+apply from: "$defaultProject"
+```
+
+In the sample has been used `defaultProject.gradle` as a basic template.
+
+The project includes a collection of Gradle templates to simplify project setup and configuration. These templates are located in the `gradle/templates` directory and can be used to quickly set up different types of projects:
+
+### Project Setup Templates
+
+* `defaultProject.gradle` (usage `apply from: "$defaultProject"`) - Basic project configuration
+* `defaultProjectWithSerialization.gradle` (usage `apply from: "$defaultProjectWithSerialization"`) - Project configuration with Kotlin Serialization support
+* `mppJavaProject.gradle` (usage `apply from: "$mppJavaProject"`) - Multiplatform project with Java support
+* `mppAndroidProject.gradle` (usage `apply from: "$mppAndroidProject"`) - Multiplatform project with Android support
+
+### Multiplatform Configuration Templates
+
+* `enableMPPAndroid.gradle` (usage `apply from: "$enableMPPAndroid"`) - Enable Android target in multiplatform project
+* `enableMPPJs.gradle` (usage `apply from: "$enableMPPJs"`) - Enable JavaScript target in multiplatform project
+* `enableMPPJvm.gradle` (usage `apply from: "$enableMPPJvm"`) - Enable JVM target in multiplatform project
+* `enableMPPNativeArm64.gradle` (usage `apply from: "$enableMPPNativeArm64"`) - Enable ARM64 native target
+* `enableMPPNativeX64.gradle` (usage `apply from: "$enableMPPNativeX64"`) - Enable x64 native target
+* `enableMPPWasmJs.gradle` (usage `apply from: "$enableMPPWasmJs"`) - Enable WebAssembly JavaScript target
+
+### Compose Integration Templates
+
+* `addCompose.gradle` (usage `apply from: "$addCompose"`) - Basic Compose configuration
+* `addComposeForAndroid.gradle` (usage `apply from: "$addComposeForAndroid"`) - Compose configuration for Android
+* `addComposeForDesktop.gradle` (usage `apply from: "$addComposeForDesktop"`) - Compose configuration for Desktop
+* `addComposeForJs.gradle` (usage `apply from: "$addComposeForJs"`) - Compose configuration for JavaScript
+
+### Publishing Templates
+
+* `publish.gradle` (usage `apply from: "$publish"`) - General publishing configuration
+* `publish_jvm.gradle` (usage `apply from: "$publish_jvm"`) - JVM-specific publishing configuration
+* `publish.kpsb` and `publish_jvm.kpsb` (usage `apply from: "$publish_kpsb"` and `apply from: "$publish_jvm_kpsb"`) - Publishing configuration for Kotlin Multiplatform and JVM
+
+### Combined Project Templates
+
+* `mppJvmJsWasmJsLinuxMingwProject.gradle` (usage `apply from: "$mppJvmJsWasmJsLinuxMingwProject"`) - Multiplatform project for JVM, JS, Wasm, Linux, and MinGW
+* `mppJvmJsWasmJsAndroidLinuxMingwLinuxArm64Project.gradle` (usage `apply from: "$mppJvmJsWasmJsAndroidLinuxMingwLinuxArm64Project"`) - Multiplatform project with additional Android and ARM64 support
+* `mppComposeJvmJsWasmJsAndroidLinuxMingwLinuxArm64Project.gradle` (usage `apply from: "$mppComposeJvmJsWasmJsAndroidLinuxMingwLinuxArm64Project"`) - Multiplatform project with Compose support
+* `mppProjectWithSerializationAndCompose.gradle` (usage `apply from: "$mppProjectWithSerializationAndCompose"`) - Multiplatform project with both Serialization and Compose support
