# Plugin Management & Development A plugin that contains utilities for managing your FiftyOne plugins and building new ones. ## Installation ```shell fiftyone plugins download \ https://github.com/voxel51/fiftyone-plugins \ --plugin-names @voxel51/plugins ``` Refer to the [main README](https://github.com/voxel51/fiftyone-plugins) for more information about managing downloaded plugins and developing plugins locally. ## Usage 1. Launch the App: ```py import fiftyone as fo import fiftyone.zoo as foz dataset = foz.load_zoo_dataset("quickstart") session = fo.launch_app(dataset) ``` 1. Press ``` or click the `Browse operations` action to open the Operators list 2. Select any of the operators listed below! ## Operators ### install_plugin You can use this operator to install FiftyOne plugins from within the App. This operator is essentially a wrapper around the [plugin installation methods](https://docs.voxel51.com/plugins/using_plugins.html#id2): ```py import fiftyone.plugins as fop # Plugin installation fop.download_plugin(...) ``` where the operator’s form allows you to choose between the following options: - Specify any GitHub URL that contains plugin(s) to install - Choose from any plugin listed in the [FiftyOne Plugins README](https://github.com/voxel51/fiftyone-plugins) to install ### manage_plugins You can use this operator to manage your FiftyOne plugins from within the App. This operator is essentially a wrapper around the following [plugin methods](https://docs.voxel51.com/plugins/using_plugins.html#managing-plugins): ```py import fiftyone.plugins as fop # Plugin enablement fop.list_plugins() fop.enable_plugin(name) fop.disable_plugin(name) # Plugin package requirements fop.load_plugin_requirements(name) fop.ensure_plugin_requirements(name) ``` where the operator’s form allows you to navigate between the available actions. ### build_plugin_component  This operator walks you through the process of building a component for a given type of input, and selecting the component’s properties. It currently supports the following component types: - **Boolean**: A way of selecting a true/false value - **Float**: A way of selecting a floating point number - **Message**: A way of displaying a message to the user - **Radio group**: A way of selecting one of a set of mutually exclusive options Each of these component types has a set of properties that can be configured. ### build_operator_skeleton  This operator walks you through the process of *creating* an operator. You can use the UI to interactively define your operator, preview the skeleton code directly in the App, and even write the generated code to disk!
