はじめる

KMPコンテストスターターキット(ニックネームココ)は、Google PlayとApp Storeで制作グレードアプリからアイデアを変換するための最速の方法です。 KMP を始めたい場合は、[https://kotlinlang.org/docs/multiplatform/quickstart.html] で「KMP Quickstart」を実行し、「T1 で最初の Compose Multiplatform アプリを作成] で「KMP Quickstart」を実行してから、両方完了したら戻ってきます。

Koko を始めるには、Android Studio でこのプロジェクトを開き、エージェントのチャット パネルに Proceed with koko-getting-started skill と入力します。

Koko — KMPStarterKit

Koko is the KMP contest starter kit — a Kotlin Multiplatform + Compose Multiplatform boilerplate for building Android and iOS apps with a shared codebase.

Getting Started

We have built the KMP Contest Starter Kit (nicknamed Koko) as the fastest way to transform your idea from a production-grade app on Google Play and the App Store. If you are looking to get started with KMP, we recommend that you run through the “KMP Quickstart” at https://kotlinlang.org/docs/multiplatform/quickstart.html and the “Create Your First Compose Multiplatform app” at https://kotlinlang.org/docs/multiplatform/compose-multiplatform-create-first-app.html - and then come back once you have completed both of those.

To get started with Koko, open this project in Android Studio and type Proceed with koko-getting-started skill into the agent’s chat panel.

Cloning on Windows? This repo uses git symlinks (CLAUDE.md/GEMINI.md → AGENTS.md, .claude/skills → skills/). On Windows, clone with symlinks enabled or they become plain text files and AI-agent skill discovery silently breaks: enable Developer Mode (Settings → For developers), then git clone -c core.symlinks=true . Also note Documentation/ is a submodule — use git clone --recurse-submodules if you want the docs site locally (optional).
