 ## Understand what's a flow
 
-A flow, represented as a YAML file, is a DAG of functions, which connected via input/output dependencies, and executed based on the topology by Prompt flow executor. See [Flows](../../concepts/concept-flows.md) for more details.

 ### Understand the flow yaml
-The entry file of a flow directory is [`flow.dag.yaml`](https://github.com/microsoft/promptflow/blob/main/examples/flows/standard/web-classification/flow.dag.yaml) which describes the `DAG(Directed Acyclic Graph)` of a flow. The flow dag of this sample likes below:
