Dokka

Dokka is an API documentation engine for Kotlin that performs the same function as the Javadoc tool for Java, but it's modern and highly pluggable.

Just like Kotlin itself, Dokka supports mixed-language projects (Kotlin/Java). It understands KDoc comments in Kotlin source files as well as Javadoc comments in Java files, and can generate documentation in multiple formats including its own HTML format, Java's Javadoc lookalike and Markdown.

Some libraries that use Dokka for API reference docs:

• kotlinx.coroutines
• kotlinx.serialization
• Ktor
• Spring Framework

---

Dokka provides support for the following build systems:

• Gradle (preferred)
• Maven
• Command line

---

Dokka is also very pluggable and comes with convenient plugin and extension point API.

You can write a plugin to support mermaid.js diagrams, mathjax formulas or even write custom processing of your own tags and annotations.
