# Add a module to an existing tenant or site

When you create a new tenant or site, the wizard lets you select the modules that you want to include. When you have an existing tenant or site and want to add modules later, you can add modules to a specific tenant or site or use the SXA bulk module installer to install modules for multiple tenants or sites.
