# Workflows Typically, when we refer to a *Workflow* we're actually talking about either a Workflow Definition or a Workflow Run. ### Workflow Definition A Workflow Definition outlines the steps that a Workflow Run will perform. In Wundaflow, a Workflow Definition is named using kebab-case, e.g.: `send-notification-email`. Workflow Definitions are created within the Wundaflow UI and are made up of at least one Workflow Task. Each Workflow Definition can be viewed in a similar way to a step-function - that is, each task (or, step) must execute successfully before the workflow will move to the next. #### Workflow Definition Versioning As with all engineering projects, Workflow Definitions may need to change over time. We support versioning using a simple incrementing integer. Workflow Runs can be started using **latest** or by specifying the `version` number required. ### Workflow Run A Workflow Run is a specific instance (execution) of a Workflow Definition. Each instance of a Workflow Run can be identified within Wundaflow using a prefixed unique ID (e.g., `flow_4eC39HqLyjWDarjtT1zdp7dc`). Each Workflow Run starts with an injected context that is persisted throughout the life of the Workflow Run. For a Run triggered from a blockchain event, this would include the related `transaction` and `block` objects. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.wundaflow.com/core-concepts/workflows.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
