# Type definitions

This article describes the type definitions used by LiSA Library for the Handlebars.js templates' input objects.

According to your custom sections config (see Configuration options ), if provided, or the default sections config, LiSA Library creates an array of Section objects and passes it to the Handlebars.js template:

```
interface LibraryInputObject {
  sections: Section[];
}
```
