# Elide Overview

> What Elide is, where to start, and the commands you will use most

Elide is one binary that runs JavaScript, TypeScript, Python, Java, Kotlin, and WebAssembly, and builds, tests,
formats, and installs dependencies for your projects.

## Start here

1. [Install Elide](https://elide.help/docs/installation).
2. [Run your first program](https://elide.help/docs/getting-started).
3. Pick a language: [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).

With `--interop`, languages share one process; a REPL session can pass values between them:

## Common commands

```bash
elide run app.ts                 # run a file
elide python script.py           # run Python with CPython-style arguments
elide repl                       # interactive REPL
elide init                       # start a new project from a template
elide adopt                      # migrate an existing project with an AI coding agent
elide install                    # install Maven dependencies
elide install --ecosystems=npm   # install npm dependencies
elide build                      # build the project
elide test                       # run tests
elide format -- src              # format Java and Kotlin sources
elide serve --no-tui ./dist      # serve a directory over HTTP
elide --help-all                 # every command and flag
elide help <topic>               # any page of these docs, in the terminal
```
