# Plugin Installation

:::{index} Plugin Installation
:::

## Preinstalled Plugins
Some plugins are built into and packaged with Arelle.
These plugins are located in the [source code][plugins-source] under `/arelle/plugins`.
No additional installation steps are necessary for these plugins.
Activate pre-installed plugins [via the GUI using Select][gui-select] or [via CLI by name][cli-name].

## Installing Plugins via Package Manager
If you installed Arelle [from source][install-from-source],
published plugins can be installed by your Python package manager of choice.

Example:
```bash
pip install ixbrl-viewer
```
Activate plugins installed with this method [via the GUI using Select][gui-select] or [via CLI by name][cli-name].

## Installing Plugins Manually
If the plugin you are using is not available via package manager, 
or you would like to run a plugin you are developing locally,
plugins can also be installed anywhere Arelle can access on your local file system.
You can then activate manually installed plugins [via the GUI using Browse][gui-browse] or [via CLI by path][cli-path].

Alternatively, if you are running Arelle [from source][install-from-source], 
you can place your plugin in the preinstalled plugins directory (`arelle/plugins`)
to allow your plugin to be treated as a [preinstalled plugin][preinstalled-plugins] and activated by name.
