+# Dynamic Agent
+
+Build a **Dynamic Agent** flow for an agentic application using the CrewAI.
+
+An **agent** uses an LLM as its "brain" to reason through tasks and select among the connected tools to complete them.
+
+This flow uses [CrewAI](https://docs.crewai.com/) to manage a [Hierarchical crew](https://docs.crewai.com/how-to/Hierarchical/) of **Agents** as they perform a sequence of **Tasks**.
+
+CrewAI agents have **Roles**, **Goals**, and **Backstories** that define their behavior and interactions with other agents. Agents in a Hierarchical Crew are managed by a single agent with a **Manager** role, which is connected to an **Open AI** LLM component to reason through the tasks and select the appropriate tools to complete them.
+
+This flow is "dynamic" because it uses the **Chat input** component's text to define a CrewAI agent's Role, Goal, and Backstory. The created agent then uses the connected tools to research and complete the **Task** created from the **Chat input** component.
+
+## Prerequisites
+
+To use this flow, you need an [OpenAI API key](https://platform.openai.com/) and a [Search API key](https://www.searchapi.io/).
+
+## Open Langflow and start a new project
+
+Click **New Project**, and then select the **Dynamic Agent** project.
+
+This opens a starter project with the necessary components to run an agentic application using CrewAI.
+
+The **Dynamic Agent** flow consists of these components:
+
+* The **Chat Input** component accepts user input to the chat.
+* The **Prompt** component combines the user input with a user-defined prompt.
+* The **OpenAI** model component sends the user input and prompt to the OpenAI API and receives a response.
+* The **Chat Output** component prints the flow's output to the chat.
+* The **CrewAI Agent** component is an autonomous unit programmed to perform tasks, make decisions, and communicate with other agents.
+* The **Crew AI Crew** component represents a collaborative group of agents working together to achieve a set of tasks. This Crew can manage work **sequentially** or **hierarchically**.
+* The **Crew AI Task** component is a specific assignment to be completed by agents.
+This task can be **sequential** or **hierarchical** depending on the Crew's configuration.
+* The **SearchAPI** tool performs web searches using the **SearchAPI.io** API.
+* The **Yahoo Finance News Tool** component creates a tool for retrieving news from Yahoo Finance.
+
+## Run the Dynamic Agent flow
+
+1. Add your credentials to the OpenAI and SearchAPI components using Langflow's Global Variables:
+   - Click **Settings**, then **Global Variables**.
+   - Click **Add New**.
+   - Name your variable and paste your API key in the **Value** field.
+   - In the **Apply To Fields** field, select the field to apply this variable to.
+   - Click **Save Variable**.
+2. In the **Chat output** component, click ▶️ Play to start the end-to-end application flow.
+   A **Chat output built successfully** message and a ✅ Check on all components indicate that the flow ran successfully.
+3. Click **Playground** to start a chat session.
+   You should receive a detailed, helpful answer to the question defined in the **Chat input** component.
+
+Now that your query has completed the journey from **Chat input** to **Chat output**, you have completed the **Dynamic Agent** flow.
