The Bitwarden CLI is written with TypeScript and Node.js. The CLI can be run on Windows, macOS, and Linux distributions.
# Download/Install
You can install the CLI two different ways:
1. If you already have the Node.js runtime installed on your system, you can simply install the CLI using NPM. NPM makes it way to keep your installation updated as well.
```bash
npm install -g @bitwarden/cli
```
2. We provide natively packaged versions of the CLI for each operating system which have no requirements on installing the Node.js runtime. You can obtain these from the [downloads section](https://bitwarden.com/#download) on our website.
You can then run commands from the `./build` folder:
```bash
node ./build/bw.js login
```
