+# Startup [![Maven Central](https://img.shields.io/maven-central/v/dev.inmo/micro_utils.common?label=latest_version&style=flat-square)](https://github.com/InsanusMokrassar/MicroUtils)
+
+* **Plugins Package**: `dev.inmo:micro_utils.startup.plugin`
+* **Launcher Package**: `dev.inmo:micro_utils.startup.launcher`
+
+This package contains unified simple `Plugin`/`Launcher` tools for separating of your apps parts
+
+## Plugin
+
+To define plugin, you must use `StartPlugin` as supertype for your plugin. Restrictions are simple: plugins must be an `object` or `class` with empty constructor. Basic sample is here:
+
+```kotlin
+object YourPlugin : StartPlugin {
+    // Body of your plugin
+}
+```
+
+Each plugin may contains to parts:
+
+* `setupDI` function to set up DI part
+* `startPlugin` function to start plugin
+
+```kotlin
+object YourPlugin : StartPlugin {
+    override fun Module.setupDI(config: JsonObject) {
+        // here you may setup any DI content you wish to be available in context of current Koin module
+    }
+    override fun startPlugin(koin: Koin) {
+        // all staff from setupDI and the same function of other plugins is available in koin
+    }
+}
+```
+
+## Launcher
+
+Basically, launcher module can be used to start application directly from `gradle`. Let's imagine you have this gradle groovy config:
+
+```groovy
+plugins {
+    id 'org.jetbrains.kotlin.jvm'
+    id "org.jetbrains.kotlin.plugin.serialization"
+    id 'application'
+}
+
+dependencies {
+    // kotlin and other dependencies
+    implementation ("dev.inmo:micro_utils.startup.launcher:$latest_version")
+}
+
+application {
+    mainClassName = 'dev.inmo.micro_utils.startup.launcher.MainKt'
+}
+```
+
+You will be able to run your project with gradle command `./gradlew run --args="path/to/config.json"`. `config.json` must contains something like:
+
+```json
+{
+    "plugins": [
+        "dev.inmo.micro_utils.startup.launcher.HelloWorldPlugin"
+    ]
+}
+```
+
+In current case you will see in logger different logs about launching including log from `HelloWorldPlugin` with text `Hello world`.
