[//]: # (title: Markdown)

{type="warning"}

Dokka is able to generate documentation in [GitHub Flavored](#gfm) and [Jekyll](#jekyll) compatible Markdown.

These formats give you more freedom in terms of hosting documentation as the output can be embedded right into your 
documentation website. For example, see [OkHttp's API reference](https://square.github.io/okhttp/4.x/okhttp/okhttp3/)
pages.

Markdown output formats are implemented as [Dokka plugins](dokka-plugins.md), maintained by the Dokka team, and 
they are open source.

## GFM

The GFM output format generates documentation in [GitHub Flavored Markdown](https://github.github.com/gfm/).

<tabs group="build-script">
<tab title="Gradle" group-key="kotlin">

The [Gradle plugin for Dokka](dokka-gradle.md) comes with the GFM output format included. You can use the following tasks with it:

| **Task**              | **Description**                                                                                                                                                                                                                         |
|-----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `dokkaGfm`            | Generates GFM documentation for a single project.                                                                                                                                                                                       |
| `dokkaGfmMultiModule` | A [`MultiModule`](dokka-gradle.md#multi-project-builds) task created only for parent projects in multi-project builds. It generates documentation for subprojects and collects all outputs in a single place with a common table of contents. |
| `dokkaGfmCollector`   | A [`Collector`](dokka-gradle.md#collector-tasks) task created only for parent projects in multi-project builds. It calls `dokkaGfm` for every subproject and merges all outputs into a single virtual project.                                |

</tab>
<tab title="Maven" group-key="groovy">

Since GFM format is implemented as a [Dokka plugin](dokka-plugins.md#apply-dokka-plugins), you need to apply it as a plugin
dependency:

```xml
<plugin>
    <groupId>org.jetbrains.dokka</groupId>
    <artifactId>dokka-maven-plugin</artifactId>
    ...
    <configuration>
        <dokkaPlugins>
            <plugin>
                <groupId>org.jetbrains.dokka</groupId>
                <artifactId>gfm-plugin</artifactId>
                <version>%dokkaVersion%</version>
            </plugin>
        </dokkaPlugins>
    </configuration>
</plugin>
```

After configuring this, running the `dokka:dokka` goal produces documentation in GFM format.

For more information, see the Mavin plugin documentation for [Other output formats](dokka-maven.md#other-output-formats).

</tab>
<tab title="CLI" group-key="cli">

Since GFM format is implemented as a [Dokka plugin](dokka-plugins.md#apply-dokka-plugins), you need to 
[download the JAR file]((https://repo1.maven.org/maven2/org/jetbrains/dokka/gfm-plugin/%dokkaVersion%/gfm-plugin-%dokkaVersion%.jar))
and pass it to `pluginsClasspath`.

Via [command line options](dokka-cli.md#run-with-command-line-options):

```Bash
java -jar dokka-cli-%dokkaVersion%.jar \
     -pluginsClasspath "./dokka-base-%dokkaVersion%.jar;...;./gfm-plugin-%dokkaVersion%.jar" \
     ...
```

Via [JSON configuration](dokka-cli.md#run-with-json-configuration):

```json
{
  ...
  "pluginsClasspath": [
    "./dokka-base-%dokkaVersion%.jar",
    "...",
    "./gfm-plugin-%dokkaVersion%.jar"
  ],
  ...
}
```

For more information, see the CLI runner's documentation for [Other output formats](dokka-cli.md#other-output-formats).

</tab>
</tabs>

You can find the source code [on GitHub](https://github.com/Kotlin/dokka/tree/%dokkaVersion%/plugins/gfm).

## Jekyll

The Jekyll output format generates documentation in [Jekyll](https://jekyllrb.com/) compatible Markdown.

<tabs group="build-script">
<tab title="Gradle" group-key="kotlin">

The [Gradle plugin for Dokka](dokka-gradle.md) comes with the Jekyll output format included. You can use the following tasks with it:

| **Task**                 | **Description**                                                                                                                                                                                                                         |
|--------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| `dokkaJekyllMultiModule` | A [`MultiModule`](dokka-gradle.md#multi-project-builds) task created only for parent projects in multi-project builds. It generates documentation for subprojects and collects all outputs in a single place with a common table of contents. |
| `dokkaJekyllCollector`   | A [`Collector`](dokka-gradle.md#collector-tasks) task created only for parent projects in multi-project builds. It calls `dokkaJekyll` for every subproject and merges all outputs into a single virtual project.                             |

This format is also based on [GFM](#gfm) format, so you need to provide it as a dependency as well. Both JARs need to be passed to 
`pluginsClasspath`:

Via [command line options](dokka-cli.md#run-with-command-line-options):

```Bash
java -jar dokka-cli-%dokkaVersion%.jar \
     -pluginsClasspath "./dokka-base-%dokkaVersion%.jar;...;./gfm-plugin-%dokkaVersion%.jar;./jekyll-plugin-%dokkaVersion%.jar" \

    "...",
    "./gfm-plugin-%dokkaVersion%.jar",
    "./jekyll-plugin-%dokkaVersion%.jar"
  ],
  ...
}
```
