 # 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).
-
+If you want to customize the Code Interprerter sandbox (e.g.: add a preinstalled package) you can do that by creating a [custom sandbox template](https://e2b.dev/docs/template/quickstart).
 
 ## 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
+1. Install E2B SDK
+
+```
+pip install e2b dotenv
+```
+
+2. Create a custom sandbox template:
+
+**template.py**
+
+```python
+from e2b import Template
+
+template = Template().from_template("code-interpreter-v1")
+```
+
+3. Create a build script:
 
-    ```Dockerfile
-    FROM e2bdev/code-interpreter:latest
-    ```
+**build.py**
 
-3. Copy [`start-up.sh`](./start-up.sh) to the same directory where's your `e2b.toml`
+```python
+from dotenv import load_dotenv
+from .template import template
+from e2b import Template, default_build_logger
 
-4. Run the following in the same directory where's your `e2b.toml`
-    ```sh
-    e2b template build -c "/root/.jupyter/start-up.sh"
-    ```
+load_dotenv()
 
-5. Use your custom sandbox with Code Interpreter SDK
+Template.build(
+    template,
+    alias="code-interpreter-custom",
+    cpu_count=2,
+    memory_mb=2048,
+    on_build_logs=default_build_logger(),
+)
+```
 
-   **Python**
-   ```python
-   from e2b_code_interpreter import Sandbox
-   sandbox = Sandbox.create(template="your-custom-sandbox-name")
-   execution = sandbox.run_code("print('hello')")
-   sandbox.kill()
+3. Build the template:
 
-   # 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')")
-   ```
-   
+```
+python build.py
+```
 
-   **JavaScript/TypeScript**
+4. Use the custom template:
 
-   ```js
-   import {Sandbox} from '@e2b/code-interpreter'
+```python
+from e2b import Sandbox
 
-const sandbox = await Sandbox.create({template: 'your-custom-sandbox-name'})
-const execution = await sandbox.runCode('print("hello")')
-await sandbox.kill()
-   ```
+sbx = Sandbox.create(template="code-interpreter-custom")
+execution = sbx.run_code("print('Hello, World!')")
+print(execution.logs.stdout)
+```
