# Flag templates

<View title="Developer" />

This topic explains the different types of flags available in LaunchDarkly. Flag templates are project-wide default settings for different types of flags.

<Note>
  **Modifying flag templates requires specific permissions**

  You can only modify flag templates if you have a role that allows the <code>updateProjectFlagDefaults</code> action. The LaunchDarkly Project Admin and Maintainer roles, as well as the Admin and Owner base roles, have this ability. To learn how to customize flag templates, read [Flag templates](/docs/home/flags/proj-flag-settings#flag-templates).

  If you need to make changes to one flag, you may be able to make the changes you need in the flag's right sidebar, or in its environment-specific settings. To learn more, read [Flag settings](/docs/home/flags/flag-settings).
