The community of DatoCMS users has released a number of different plugins. As we'll see later in much detail, they're basically NPM packages.
To install a new plugin to one of your projects, head over to the Settings > Plugins section of your administrative area, and press the plus button.

Once an plugin has been successfully installed, it can be assigned to one (or many) fields in one of your models. To do that navigate to a Model, select a field and navigate to the Settings > Presentation tab of the field.

To use the plugin across several fields, just repeat the above steps again for each field.
