# arkor init

> Add Arkor to an existing project.

# `arkor init`

Drops Arkor's starter files into your current directory: a [Trainer](/concepts/trainer) under `src/arkor/`, an `arkor.config.ts`, and a `dev` / `build` / `start` script trio in your `package.json`.

Use it from inside a directory you already own. For greenfield projects, use `<pm> create arkor` instead. See [Quickstart](/quickstart).

## Run it

<CodeGroup>
  ```bash pnpm theme={null}
  pnpm arkor init
  ```

  ```bash npm theme={null}
  npm arkor init
  ```

  ```bash yarn theme={null}
  yarn arkor init
  ```

  ```bash yarn-berry theme={null}
  yarn run arkor init
  ```

  ```bash bun theme={null}
  bun arkor init
  ```
</CodeGroup>

The command asks for a project name, picks a starter template, optionally runs `git init`, then installs dependencies. Take the defaults to get something working fast; come back later to customize.

## Then what

Once init finishes, the next step is:

<CodeGroup>
  ```bash pnpm theme={null}
  pnpm dev
  ```

  ```bash npm theme={null}
  npm run dev
  ```

  ```bash yarn theme={null}
  yarn dev
  ```

  ```bash bun theme={null}
  bun dev
  ```
</CodeGroup>

Studio boots at `http://127.0.0.1:4000`. From there you can trigger a training run.
