# Usage guide: Investigations starter pack

{% hint style="warning" %}
This page outlines various ways to use the pack, including use case examples.

Administrators can refer to the [Configuration guide: Investigations starter pack](/platform/library-packs/it-operations/investigations-starter-pack/configuration-guide-investigations-starter-pack.md) to set up and customize the installed content.
{% endhint %}

The **Getting started investigations** library pack enables EUC teams to leverage pre-built investigations or out-of-the-box solutions to:

* Quickly gain insights on common and recurring issues.
* Accelerate NQL proficiency within your organization by exploring the underlying queries.

## Library pack use: quick investigation execution

{% hint style="info" %}
Jump to [Use cases](#use-cases) on this page to see relevant scenario applications.
{% endhint %}

Find in the [Configuration guide: Investigations starter pack](/platform/library-packs/it-operations/investigations-starter-pack/configuration-guide-investigations-starter-pack.md#documentation-contentanddependencies) a purpose/description for each pre-defined library investigation. These investigations are ready to use once installed.

You can quickly [customize and reuse](/platform/library-packs/it-operations/investigations-starter-pack/configuration-guide-investigations-starter-pack.md#documentation-configurationguide) these library investigations as-is or as templates by, for example, adding additional fields or columns to incorporate more information into the investigation results table.

Refer to the [Investigations ](/platform/user-guide/investigations.md)documentation to learn more about managing, editing, running, and sharing investigations.

## Use case example: Investigating system errors versus devices

Use **System crashes by error label** predefined investigation to investigate **System crashes**.

Without relying on [Nexthink Assist](https://docs.nexthink.com/platform/user-guide/search-and-nexthink-assist/using-nexthink-assist#query-data-with-assist) to query **System crashes** from scratch, you can simply edit the installed **System crashes by error label** library investigation and add the **Device model** and **Hardware → Manufacturer** field columns to correlate specific errors with particular models or manufacturers.

Both the [NQL editor](/platform/user-guide/investigations/creating-investigations/nql-editor.md) and [Visual editor](/platform/user-guide/investigations/creating-investigations/visual-editor.md) support investigations installed from the library.

The image below displays the device model and manufacturer associated with **System crashes**.
