# Initial setup

Once the Portainer Server has been deployed, and you have navigated to the instance's URL, you are ready for the initial setup.

## Creating the first user

Your first user will be an administrator. The username defaults to `admin` but you can change it if you prefer. The password must be at least 12 characters long and meet the listed password requirements.

## Connecting Portainer to your environments

Once the admin user has been created, the **Environment Wizard** will automatically launch. The wizard will help get you started with Portainer.

The installation process automatically detects your local environment and sets it up for you. If you want to add additional environments to manage with this Portainer instance, click **Add Environments**. Otherwise, click **Get Started** to start using Portainer!
