It receives input, processes it, and produces output. Flows consist of [components](/Components/componentoverview) that you configure and connect in the **Workspace**. Simple Agent Pn A flow can be as simple as the [basic prompting flow](/Getstarted/quickstart), which creates an OpenAI chatbot with four components. * Each component in a flow is a **node** that performs a specific task, like an AI model or a data source. * Each component has a **Configuration** menu. Click the **Code** button on a component to see its underlying Python code. * Components are connected with **edges** to form flows. ## **Find your way around**[**​**](https://docs.langflow.org/concepts-overview#find-your-way-around) If you're new to LLM Controls, it's OK to feel a bit lost at first. We’ll take you on a tour, so you can orient yourself and start creating applications quickly. LLM Controls has four distinct regions: the [workspace](https://docs.llmcontrols.ai/Concepts/LLMCoverview#workspace%E2%80%8B) is the main area where you build your flows. The components sidebar is on the left and lists the available [components](https://docs.llmcontrols.ai/Concepts/LLMCoverview#components%E2%80%8B). The [playground](https://docs.llmcontrols.ai/Concepts/LLMCoverview#playground%E2%80%8B) and [publish pane](https://docs.llmcontrols.ai/Concepts/LLMCoverview#publish-pane%E2%80%8B) are available in the upper right corner. ## **Workspace**[**​**](https://docs.langflow.org/concepts-overview#workspace) The **workspace** is where you create AI applications by connecting and running components in flows. * Click and drag the workspace to move it left, right, up, and down. * Scroll up and down to zoom in and out of the workspace, or use the **Zoom In** and **Zoom Out** controls. * Click **Fit To Zoom** to center the workspace on the current flow. * Click **Lock** to lock the workspace in place, preventing accidental movement. * Click **Add Note** to add a note to your flow, similar to commenting in code. Workspace Pn ## **Components**[**​**](https://docs.langflow.org/concepts-overview#components) A **component** is a single building block within a flow and consists of inputs, outputs, and parameters that define its functionality. To add a component to your flow, drag it from the sidebar onto the workspace. To connect components, drag a line from the output handle of one component to the input handle of another. For more information, see [Components overview](/Components/componentoverview). Overview ## **Playground**[**​**](https://docs.langflow.org/concepts-overview#playground) The **Playground** executes the current flow in the workspace. Chat with your flow, view inputs and outputs, and modify your AI's memories to tune your responses in real time. Either the **Chat Input** or **Chat Output** component can be opened in the **Playground** and tested in real time. For more information, see the [Playground](/Concepts/playground). Playground(2) Pn ## **Publish pane**[**​**](https://docs.langflow.org/concepts-overview#publish-pane) The **Publish** pane provides code templates to integrate your flows into external applications. For more information, see the [Publish pane](/Concepts/publish-flows). Publish Pane Pn ## **View logs**[**​**](https://docs.langflow.org/concepts-overview#view-logs) The **Logs** pane provides a detailed record of all component executions within a workspace. To access the **Logs** pane, click your **Flow Name** and then select **Logs**. Logs Pn ## **Projects**[**​**](https://docs.langflow.org/concepts-overview#projects) The **Projects** page displays all the flows you've created in the LLM Controls workspace. Project Pn **Starter Project** is the default space where all new projects are initially stored. To create a new project, click **Create new project**. To upload a flow to your project, click **Upload a flow**. To delete a flow from your project, click a flow's checkbox to select it, and then click **Delete**. You can select multiple flows in a single action. ## **File management**[**​**](https://docs.langflow.org/concepts-overview#file-management) Upload, store, and manage files in LLM Controls' **File management** system. For more on managing your files, see [Manage files](/Concepts/manage-files). File Management Pn ## **Options menu**[**​**](https://docs.langflow.org/concepts-overview#options-menu) The dropdown menu labeled with the project name offers several management and customization options for the current flow in the LLM Controls workspace: * **New**: Create a new flow from scratch. * **Edit Details**: Adjust settings specific to the current flow, such as its name, description, and endpoint name. * **Logs**: View logs for the current project, including execution history, errors, and other runtime events. * **Import**: Import a flow or component from a JSON file into the workspace. * **Export**: Export the current flow as a JSON file. * **Undo**: Revert the last action taken in the project. Keyboard shortcut: Control+Z(or on macOS). * **Redo**: Reapply a previously undone action. Keyboard shortcut: Control+Y(or on macOS). * **Refresh All**: Refresh all components and delete cache. Option Menu Pn ## **Settings** In the LLM Controls header, click your profile icon, and then select **Settings** to access general LLM Controls settings, including global variables, LLM Controls API keys, keyboard shortcuts, and log messages.
