If you're a developer looking to get started with Kotlin, one of the first things you'll need to do is download and set up the language on your local machine. This guide will walk you through the process of downloading Kotlin from GitHub, the official source, and setting it up for development.
Why Kotlin and Why GitHub?
Kotlin is a modern, statically-typed programming language that runs on the JVM and is fully interoperable with Java. It's designed to be more concise, safer, and more expressive than Java. GitHub, on the other hand, is a web-based hosting service for version control using Git. It's where the Kotlin team maintains the official Kotlin repository.
Downloading Kotlin from GitHub ensures you're using the official, up-to-date version of the language. It also allows you to contribute to Kotlin's development if you're so inclined, as you'll have the full source code at your fingertips.

Prerequisites
- A GitHub account (optional, but recommended for contributing)
- Git installed on your local machine
- A code editor or IDE (like IntelliJ IDEA, which comes with Kotlin support)
Setting Up Git
Before you start, make sure you have Git installed and configured. You can download Git from the official website. After installation, open your terminal or command prompt and type:
git config --global user.name "Your Name" git config --global user.email "your.email@example.com"
Downloading Kotlin from GitHub
Using Git
The recommended way to download Kotlin is by cloning the repository using Git. This allows you to easily update your local copy of Kotlin with the latest changes. Here's how:
- Open your terminal or command prompt.
- Navigate to the directory where you want to clone the repository.
- Clone the Kotlin repository using the following command:
git clone https://github.com/JetBrains/kotlin.git
Downloading as a ZIP
If you just want to download Kotlin without using Git, you can download the repository as a ZIP file. Here's how:

- Go to the Kotlin GitHub page.
- Click the green "Code" button.
- Select "Download ZIP".
- Extract the ZIP file to your desired location.
Setting Up Kotlin for Development
Once you have Kotlin downloaded, you can set it up for development. If you're using IntelliJ IDEA, you can open the project directly. Otherwise, you can use the following commands to compile and run Kotlin code:
| Command | Description |
|---|---|
| ./gradlew build | Compiles the Kotlin standard library and tests. |
| ./gradlew runExamples | Runs the Kotlin examples. |
For more information on building and running Kotlin, see the official Kotlin documentation.
That's it! You've successfully downloaded Kotlin from GitHub and set it up for development. Happy coding!
