## What it is
Dokka is an API documentation engine for Kotlin that understands KDoc and Javadoc comments in mixed-language projects. It generates documentation in HTML, Markdown (GFM/Jekyll), and Javadoc-style formats via Gradle, Maven, or CLI runners, and is highly extensible through plugins.

## Use cases
- generate API reference docs for a Kotlin library
- produce javadoc.jar for publishing to Maven Central
- document a mixed Kotlin and Java codebase
- generate Markdown documentation for a Kotlin multiplatform project
- host Kotlin API docs on GitHub Pages
- customize documentation rendering with a Dokka plugin

## When to choose
- you maintain a Kotlin or Kotlin/Java library and need API reference documentation
- you need javadoc.jar artifacts for Maven publishing
- you want HTML or Markdown docs generated from KDoc comments
- you need multiplatform or multi-module documentation support

## When to avoid
- your project is pure Java and standard Javadoc suffices
- you need hand-written guides rather than generated API references
- you need Javadoc format for multi-project or multiplatform builds (unsupported)

## Facets
- artifact type: library
- maturity: active
- function: documentation, api-documentation, build-tool, cli, plugin-system
- domain: documentation, developer-tools, programming-languages, apis
- platform: jvm, cli, cross-platform
- tags: kdoc, javadoc, kotlin, gradle-plugin, maven-plugin, static-docs, jetbrains, gradle, maven
