# Elide Overview

> Install Elide, run your first program, and find guides and references for JavaScript, TypeScript, Python, Java, Kotlin and WebAssembly.

Run JavaScript, TypeScript, Python, Java, Kotlin and WebAssembly with Elide. Use its built-in tools to install
dependencies, build projects and run tests.

## Start here

1. [Install Elide](https://elide.help/docs/installation).
2. Pick a first-program guide: [JavaScript and TypeScript](https://elide.help/docs/web), [Python](https://elide.help/docs/python),
   [Java and Kotlin](https://elide.help/docs/jvm), or [WebAssembly](https://elide.help/docs/wasm).

Already have a project? [Choose how to use it with Elide](https://elide.help/docs/getting-started#use-an-existing-project): keep your build
tools, migrate a JVM build, or run scripts from an existing manifest.
