# Using custom sandbox with Code Interpreter SDK If you want to customize the Code Interprerter sandbox (e.g.: add a preinstalled package) you can do that by using a [custom sandbox template](https://e2b.dev/docs/sandbox-template). ## Step-by-step guide 1. Create custom sandbox by following [this guide](https://e2b.dev/docs/sandbox-template) 2. Use prebuilt [E2B Code Interpreter image](https://hub.docker.com/r/e2bdev/code-interpreter) by replacing the `FROM` command in your `e2b.Dockerfile` with following ```Dockerfile FROM e2bdev/code-interpreter:latest ``` 3. Copy [`start-up.sh`](./start-up.sh) to the same directory where's your `e2b.toml` 4. Run the following in the same directory where's your `e2b.toml` ```sh e2b template build -c "/root/.jupyter/start-up.sh" ``` 5. Use your custom sandbox with Code Interpreter SDK **Python** ```python from e2b_code_interpreter import Sandbox sandbox = Sandbox.create(template="your-custom-sandbox-name") execution = sandbox.run_code("print('hello')") sandbox.kill() # Or you can use `with` which handles closing the sandbox for you with Sandbox.create(template="your-custom-sandbox-name") as sandbox: execution = sandbox.run_code("print('hello')") ``` **JavaScript/TypeScript** ```js import {Sandbox} from '@e2b/code-interpreter' const sandbox = await Sandbox.create({template: 'your-custom-sandbox-name'}) const execution = await sandbox.runCode('print("hello")') await sandbox.kill() ```
