# Create a profile

To create a new profile, open the [Addressables Profile window](addressables-profiles-window.md), select __Create__ > __Profile__. A new profile row appears in the table.

Every profile must define a value for every variable. When you create a new profile, Addressables copies all values from the selected profile.

## Set the active profile

The active profile determines the set of variables used when you run a build script.

To set the active profile, either:

1. Open the Groups window (menu: __Window > Asset Management > Addressables > Groups__).
2. Click the __Profile__ menu in the toolbar.
3. Choose the profile to make active.

Or:

1. Open the Profiles window (menu: __Window > Asset Management > Addressables > Profiles__).
2. Right-click on a profile to open the context menu.
3. Choose __Set Active__.
