# Option 2: Web Interface
You have the choice to create a new file or upload your existing files through the web interface.
### Create a New File
1\. Start by selecting the **Files and version** tab, and then clicking **Contribute** → **Create a new file.**
2\. And then you can choose a name for your file, add content, and save your file by clicking on "Commit new file".
{% hint style="info" %}
When deploying a Space, provide either a **`dockerfile`** or **`deploy.yaml`**, or both. If both are provided, **`deploy.yaml`** takes precedence and will be executed while the **`dockerfile`**will be ignored.
{% endhint %}
### Upload Files
1.Start by selecting the **Files and version** tab, and then clicking **Contribute** → **Upload files.**
Note that, if you prefer, you can also utilize [**Lagrange-cli**](/spaces/intro/lagrange-cli.md) to upload code files to your Space
