+## Dokka custom format example
+
+This example demonstrates how to override `.css` styles and add custom images as assets, allowing
+you to change the logo used in the header.
+
+You can see up-to-date documentation generated for this example on 
+[GitHub Pages](https://kotlin.github.io/dokka/examples/dokka-customFormat-example/html/index.html).
+
+![screenshot demonstration of output](demo.png)
+
+### Running
+
+Run `dokkaHtml` task to generate documentation with the custom logo in place:
+
+```bash

+# Dokka Kotlin-as-Java plugin example
+
+This example demonstrates how you can apply a Dokka plugin in a simple Gradle project.
+
+In particular, it applies [Kotlin as Java](../../../plugins/kotlin-as-java) Dokka plugin that renders all
+Kotlin signatures as Java signatures.
+
+You can see up-to-date documentation generated for this example on
+[GitHub Pages](https://kotlin.github.io/dokka/examples/dokka-kotlinAsJava-example/html/index.html).
+

+# Dokka Library publishing example
+
+This example demonstrates how you can integrate Dokka into the publishing process of your library, adding
+documentation generated by Dokka as artifacts.
+
+This is useful because some repositories, like Maven Central, require documentation (`javadoc.jar`) to be published
+alongside library artifacts.
+
+You can also use services like [javadoc.io](https://javadoc.io/) to host of your library's API documentation for free 
+and without any additional setup - it will take documentation pages straight from the published artifact. It works with 
+both HTML and Javadoc formats as demonstrated by 
+[com.trib3's Javadocs](https://javadoc.io/doc/com.trib3/server/latest/index.html).
+
+## Running
+
+Run `dokkaHtml` task to generate documentation for this example:
+
+```bash
+./gradlew dokkaHtml
+```
+
+### Javadoc jar
+
+Run `dokkaJavadocJar` task to create a jar file that contains documentation generated in Dokka's Javadoc format.
+
+```Bash
+./gradlew dokkaJavadocJar
+```
+
+After that, you can find the jar under `build/libs/dokka-library-publishing-example-javadoc.jar`
+
+### HTML jar
+
+
+Run `dokkaHtmlJar` task to create a jar file that contains documentation generated in Dokka's HTML format.
+
+```Bash
+./gradlew dokkaHtmlJar
+```
+
+After that, you can find the jar under `build/libs/dokka-library-publishing-example-html.jar`

+
+You can also learn how to set Dokka's version in [gradle.properties](gradle.properties) using `pluginManagement`

+
+____
+
+You can see up-to-date documentation generated for this example on

+
+Run `dokkaHtmlMultiModule` task to generate documentation for this example:
+
+```bash
+./gradlew dokkaHtmlMultiModule
+```
+
+It will generate complete documentation for the root project and its subprojects, with a common

+# Dokka Multiplatform example
+
+This example demonstrates Dokka's configuration and output for a simple 
+[Kotlin Multiplatform](https://kotlinlang.org/docs/multiplatform.html) project.
+
+It contains [Kotlin source sets](https://kotlinlang.org/docs/multiplatform-discover-project.html#source-sets) for different
+platforms that are automatically picked up by Dokka from the Kotlin Gradle Plugin, and an additional custom source
+set known to Dokka only.
+
+The example demonstrates the following things:
+
+* Documentation for common code
+* Documentation for expect/actual declarations available via tabs
+* Documentation for platform-specific declarations, including functions from different source sets, but 
+  with clashing names
+* Use of Platform-specific API, such as `CPointer` from `kotlinx.cinterop`
+
+You can see up-to-date documentation generated for this example on
+[GitHub Pages](https://kotlin.github.io/dokka/examples/dokka-multiplatform-example/html/index.html).
+
+![screenshot demonstration of output](demo.png)
+
+### Running
+
+Run `dokkaHtml` task in order to generate documentation for this example:
+
+```bash
+./gradlew dokkaHtml
+```

+# Dokka Versioning MultiModule example
+
+This example demonstrates configuration of Dokka's [versioning plugin](../../../plugins/versioning), which
+allows readers to navigate through different versions of your API reference documentation.
+
+The example contains some code that exists only in the current documentation version `1.0`. You will not see
+this code in the previous version `0.9`, which is located in the [previousDocVersions](previousDocVersions) directory.
+
+___
+
+You can see up-to-date documentation generated for this example on
+[GitHub Pages](https://kotlin.github.io/dokka/examples/dokka-versioning-multimodule-example/htmlMultiModule/index.html).
+
+![screenshot demonstration of output](demo.png)
+
+### Running
+
+Run `dokkaHtmlMultiModule` task to generate documentation for this example:
+
+```bash
+./gradlew dokkaHtmlMultiModule
+```
+
+It will generate complete documentation for the root project and its subprojects, with the version navigation
+dropdown menu.

+ *
+ * The `SamWithReceiver` plugin is automatically applied by the `kotlin-dsl` plugin.
+ * It converts all [org.gradle.api.Action] so the parameter is the receiver:
+ *
+ * ```
+ * // with SamWithReceiver ✅
+ * tasks.configureEach {
+ *   val task: Task = this
+ * }
+ *
+ * // without SamWithReceiver
+ * tasks.configureEach { it ->
+ *   val task: Task = it
+ * }
+ * ```
+ *
+ * This is nice because it means that the Dokka Gradle Plugin more closely matches `build.gradle.kts` files.
+ *
+ * However, [IntelliJ is bugged](https://youtrack.jetbrains.com/issue/KTIJ-14684) and doesn't
+ * acknowledge that `SamWithReceiver` has been applied in test sources. The code works and compiles,
+ * but IntelliJ shows red errors.
+ *
+ * These functions are workarounds, and should be removed ASAP.
