# Kotlin Community + Hacktoberfest 2021

It's that time of the year again! Hacktoberfest 2021 is up and running!

As a good tradition, we've decided to highlight the projects of our community members. Feel free to pick something interesting from the list, or get in touch via Kotlin Community Meta to get your project mentioned here.

TelegramBotAPI

channel | chat | api docs | tutorial

This is a set of libraries that provide you opportunity for more strictly typed work with Telegram Bot API. Developed by @InsanusMokrassar, it has a great and fun-to-use DSL which not just covers most of Bot APIs, but also provides convenient coroutine-based abstraction, which makes bot development enjoyable!

The project would like some help with following:

• Add kdocs (or a lot of KDocs :) )

kAppKit

kAppKit is a project that provides type-safe bindings to native Objective C macOS API, that allow to create native interfaces and call system functions and UI.

The project would like some help with following:

• Add kDocs to already implemented classes using official Apple Developer documentation, with guidance by already built.

KMath

Goals of the project:

• Provide a flexible and powerful API to work with mathematics abstractions in Kotlin-multiplatform (JVM, JS and Native).
• Provide basic multiplatform implementations for those abstractions (without significant performance optimization).
• Provide bindings and wrappers with those abstractions for popular optimized platform libraries.

The project would like some help with following:

• Reimplement methods from kotlin-statistics
