# Start
|
|
|
|
### Definition
|
|
|
|
Define the initial parameters for starting a workflow.
|
|
|
|
You can customize the input variables for initiating the workflow in the start node. Every workflow requires a start node.
|
|

The start node supports defining input variables of four types:
|
|
|
|
* Text
|
|
* Paragraph
|
|
* Dropdown Options
|
|
* Number
|
|
* File (coming soon)

|
|
|
|
Once configured, the workflow will prompt for the values of the variables defined in the start node during execution.

Tip: In Chatflow, the start node provides built-in system variables: `sys.query` and `sys.files`.
|
|
|
|
`sys.query` is used for user input questions in conversational applications.
|
|
|
|
`sys.files` is used for file uploads in conversations, such as uploading an image, which needs to be used in conjunction with an image understanding model.
