# Overview

The Blueprints section is used to compose provisioning catalogs. The Blueprints section is composed of:

- Instance Types
- Layouts
- Node Types
- App Blueprints
- Catalog Items
- Cluster Layouts

Additionally, items from Options and Templates sections are incorporated to call in custom options for users, IaaS spec files, scripts, and more. See Options and Templates within HPE Morpheus Enterprise Library for more information on creating or sourcing the items below from version control. In some cases, they may need to be pre-existing for the most efficient creation of Blueprints.

- Inputs
- Option Lists
- File Templates
- Scripts
- Spec Templates
