+
+# Getting started
+
+To get started create a new kotlin project in intellij of the type 'Browser application'
+
+![Create 'Browser Application' project](/docs/img/create-project.png)
+
+Add the 'sourceSets' block with the kotlin-komponent dependency so your build.gradle.kts looks like this:
+
+```gradle
+plugins {
+    kotlin("js") version "1.6.10"
+}
+
+group = "com.test"
+version = "1.0.0-SNAPSHOT"
+
+repositories {
+    mavenCentral()
+}
+
+dependencies {
+    api("nl.astraeus:kotlin-komponent-js:1.0.0")
+
+    testImplementation(kotlin("test"))
+}
+
+kotlin {
+    js(IR) {
+        binaries.executable()
+        browser {
+            commonWebpackConfig {
+                cssSupport.enabled = true
+            }
+        }
+    }
+}
+```
+
+Refresh the gradle project to import the dependency.
+
+There is now only one kotlin source file in the project called Simple.kt, it should look something like this:
+
+```kotin
+fun main() {
+  console.log("Hello, ${greet()}")
+}
+
+fun greet() = "world"
+```
+
+Replace the code in the file with the following for a simple click app:
+
+```kotlin
+import kotlinx.browser.document
+import kotlinx.html.button
+import kotlinx.html.div
+import kotlinx.html.hr
+import kotlinx.html.js.onClickFunction
+import nl.astraeus.komp.HtmlBuilder
+import nl.astraeus.komp.Komponent
+import nl.astraeus.komp.mutableCollectionState
+import nl.astraeus.komp.state
+import kotlin.js.Date
+
+fun main() {
+  console.log("Hello, ${greet()}")
+
+  Komponent.create(document.body!!, TestKomponent())
+}
+
+fun greet() = "world"
+
+class TestKomponent : Komponent() {
+  var clicks: Int = 0
+  val lines: MutableCollection<String> = mutableListOf()
+
+  override fun HtmlBuilder.render() {
+    div {
+      div {
+        +"Hello Komponent!"
+      }
+
+      div {
+        +"Clicks $clicks"
+      }
+
+      div {
+        button {
+          +"Click"
+          onClickFunction = {
+            clicks++
+            lines.add("click $clicks at ${Date()}")
+            requestUpdate()
+          }
+        }
+      }
+
+      hr()
+
+      for (line in lines) {
+        div {
+          + line
+        }
+      }
+
+    }
+  }
+}
+```
+
+First in the main we add our TestKomponent to the document body with the following line:
+
+```kotlin
+  Komponent.create(document.body!!, TestKomponent())
+```
+
+The TestKomponent.render method will be called to render our Komponent. 
+As you can see events can be attached inline with the on<event>Function methods.
+The requestUpdate method will call the render method again and update the page accordingly.
+
+After building the application you will find it in /build/distributions.
+
+In the index.html page you will find the following line:
+
+```html
+<div id="root"></div>
+```
+
+This line is not needed for kotlin-komponent.
+
+If you like you can use some helpers that will automatically call the requestUpdate method if
+the data changes, that would look like this:
+
+```kotlin
+  var clicks: Int by state(0)
+  val lines: MutableCollection<String> = mutableCollectionState(mutableListOf())
+```
+
+In that case you can remove the requestUpdate call from the onClickFunction.
+
+You can find a working repository of this example here: [kotlin-komponent-start](https://github.com/rnentjes/kotlin-komponent-start)

+
+# How it works
+
+When the requestUpdate call is made to the [Komponent](src/jsMain/kotlin/nl/astraeus/komp/Komponent.kt)
+the update is queued in a callback. The callback will be called after the current event is handled.
+
+If there are multiple updates requested, these are sorted so that the top Komponents get executed first. 
+This way there will not be double updates of the same komponent.
+
+The render call will be invoked and every html builder function (div, span etc.) will call the 
+different HtmlBuilder functions like onTagStart, onTagAttributeChange etc.
+
+In these functions the HtmlBuilder will compare the dom against the call being made, and it will update the DOM
+as needed.

 # Komponent

+![Gradle CI](https://github.com/rnentjes/komponent/workflows/Gradle%20CI/badge.svg)
+
 Very simple helper to build single page apps with the Kotlin javascript target using static html builders.

 See the komp-todo repository for a basic example here: [komp-todo](https://github.com/rnentjes/komp-todo)

 For a more complete example take a look at the simple-password-manager repository: [simple-password-manager](https://github.com/rnentjes/simple-password-manager)
+
+Available on maven central: "nl.astraeus:kotlin-komponent-js:1.0.0"
+
+Some getting started documentation can be found [here](docs/getting-started.md)
