# Action nodes

Appfarm Create features a built-in library of logical operations, known as *action nodes*, that can be dropped into an [action](/reference/actions.md). Each action node runs a distinct operation with customizable properties. These include [if statements](/library/action-nodes/if.md) and [foreach loops](/library/action-nodes/foreach.md) as well as [data operations](#data) and advanced functionality such as [generating PDFs](/library/action-nodes/generate-document.md) and [sending SMS](/library/action-nodes/send-sms.md).

You can add Action Nodes to an Action with drag & drop, by clicking the Action Node (will add it after the selected action node inside the selected action), or by using [Appfarm Commander](/reference/appfarm-create/appfarm-commander.md) (`CTRL/CMD + k` <i class="fa-right">:right:</i> Seach by name <i class="fa-right">:right:</i> Add the action node).

## Data

Create and manipulate data in [data sources](/reference/apps/data/data-sources.md).
