### Upload Process

1. **Select Data Source**\
   Choose from the data source types configured in your pipeline. Dify currently supports 4 types of data sources: File Upload (pdf, docx, etc.), Online Drive (Google Drive, OneDrive, etc.), Online Doc (Notion), and Web Crawler (Jina Reader, Firecrawl).
   Please visit [Dify Marketplace](https://marketplace.dify.ai/) to install additional data sources.

2. **Fill in Processing Parameters and Preview**\
   If you configured user input fields during pipeline orchestration, users will need to fill in the required parameters and variables at this step. After completing the form, click **Preview** to see chunking results. Click **Save & Process** to complete knowledge base creation and start data processing.
   <Warning>
     Important reminder: Chunk structure remains consistent with the pipeline configuration and won't change with user input parameters.
