Getting Started

View the documentation for more detailed instructions about how to set up and use Dokkatoo.

Quick start

To quickly generate documentation for your project, follow these steps.

Tip

Dokkatoo supports multiple formats, but HTML is the quickest and easiest to get started with.

1. Check the Gradle Plugin Portal to find the latest version of Dokkatoo.

2. Add the Dokkatoo plugin to your subproject:

   // build.gradle.kts
   
   plugins {
     kotlin("jvm")
     id("dev.adamko.dokkatoo-html")
   }

3. (Optional) If you'd like to combine multiple subprojects, add the Dokkatoo plugin to each subproject, and aggregate them in a single project by declaring dependencies to the subprojects.

   // build.gradle.kts
   plugins {
      id("dev.adamko.dokkatoo-html")
   }
   
   dependencies {
     // Aggregate both subproject-hello and subproject-world into the current subproject.
     // These subprojects must also have Dokkatoo applied.
     dokkatoo(project(":subproject-hello"))
     dokkatoo(project(":subproject-world"))
   }

4. Run the generation task:

   ./gradlew :dokkatooGenerate

5. View the results in ./build/dokka/

For more detailed instructions about how to set up and use Dokkatoo, and control the output, more guides are available in the docs.

• Follows Gradle best practices for plugin development, for a more stable experience.
• Faster, parallel execution.
