# AppSignal guides

Welcome to the AppSignal Guides! Here we'll guide you through every step you need to take to integrate AppSignal with your application successfully. Our guides were written with you in mind, covering everything from adding a new application to finding slow queries.

Don't worry if you get lost. Our [Support Page](/support) will help you get back on track.

## Contents

* New to AppSignal? We recommend following our [Getting Started Guides](#getting-started-guides)
* Exploring more features? Read up on our [Feature Guides](#feature-guides)
* Need help managing your application? Check out our [Application Management Guides](#application-management-guides)

## Getting Started Guides

AppSignal wasn't built in a day, but it can be installed in minutes. In these guides, we'll help you get set up with your AppSignal Account, show you how to install AppSignal in your application, and learn how to use it to get the most out of your application's metrics.

<Tip>
  In many of these guides you'll be interacting with AppSignal and your
  applications codebase, so before starting boot up your favourite text editor
  and grab a cup of something refreshing to drink ☕️
