# Analyze your project

> Collect data about your project and identify areas to optimize.

Use the Project Auditor window to run an analysis on your project. You can customize how Project Auditor runs in the [Preferences window](/engine/6000.5/manual/analysis/project-auditor/settings-reference.md), or you can use the [scripting APIs](/engine/6000.5/manual/analysis/project-auditor/programming.md).

## Prerequisite

To use Project Auditor, you must install the [Project Auditor Rules](https://docs.unity3d.com/Packages/com.unity.project-auditor-rules@latest) package. The Welcome view contains a link to the package when you open Project Auditor for the first time.

## Create a new report

To analyze your project and get a report, perform the following steps:

1. Open the Project Auditor window (**Window** > **Analysis** > **Project Auditor**). If you haven't installed the required [Project Auditor Rules](https://docs.unity3d.com/Packages/com.unity.project-auditor-rules@latest) package, select **Install Rules** to install it.
2. Select **Start Analysis**. If the window is already populated with data, select **New Analysis** to reset the window.

Project Auditor then analyzes your project. The analysis might take a few minutes to complete, depending on the chosen configuration and how large the project is. Once the analysis completes, Project Auditor displays a [Summary View](/engine/6000.5/manual/analysis/project-auditor/window/summary-view-reference.md) of the report.

> **Note:**
>
> By default, Project Auditor runs all [Project Areas](/engine/6000.5/manual/analysis/project-auditor/window/reference.md#project-area-views). To customize this default behavior, you can enable and disable specific Project Areas in the Preferences window.

## Load a report

To load a previously saved report:

1. Open the Project Auditor window (**Window** > **Analysis** > **Project Auditor**).
2. Select the Load icon (square with arrow), and choose the .projectauditor file to load.
