### Stop and resume

Stop the sandbox when you are done:

```bash
container stop coderunner
```

Resume the same sandbox later, preserving uploads, kernels, and installed packages:

```bash
container start coderunner
```

To start over with a clean sandbox, delete the container and run the installer again:

```bash
container delete coderunner && ./install.sh
```
