# Introduction

> A remote GPU that feels local.

Cassian gives you a GPU-powered dev environment in one command. Your files sync automatically. Your workspace persists across sessions.

```bash theme={null}
npm install -g cassian-cli
cassian login
cassian init
cassian up
cassian ssh
```

## How it works

1. **`cassian init`** creates a `cassian.yaml` config in your project
2. **`cassian up`** provisions a container with your GPUs and restores your workspace
3. **`cassian ssh`** opens a terminal with your files in `/workspace`
4. **`cassian exec`** runs commands without a terminal
5. **`cassian down`** saves your workspace and stops the instance
