Open your PDI and start building in the instance.

## Before you begin

Role required: none

## About this task

Once you have obtained a PDI, you can open the instance from
Account menu.

## Procedure

1. Sign in to the Developer Site.
2. Open the Account menu and click the Start building link.  
3. If your PDI is hibernating, wait a couple minutes for your PDI to wake up before you can access it.  
   Your PDI wakes from hibernation automatically when you sign in to the Developer site.
4. If your PDI hibernates while you are still signed in to the Developer Site, select the Refresh Instance instance action, then click the Wake Instance button to wake your PDI from hibernation.
5. If the instance is undergoing maintenance, you will need to wait for maintenance to complete before you can access your PDI.
6. If you have any issues accessing your PDI, review the [Getting instance assistance](https://servicenow-prod.fluidtopics.net/wxNVyUqsVN3mqdTY3LaQww "Get assistance for common issues accessing an instance and give feedback.") section of this guide for steps you can take.
