TrueNAS has several software branches (linear update paths) known as trains. Update profiles offer updates to the release running on your system based on specific use cases. Some profiles are not available or recommended for Enterprise customers. TrueNAS systems are shipped with the profile set for the user based on their use case.

The Update screen shows the installed version, other installation or update options, and user profiles. Some users can select a different profile option from the Select and update profile dropdown list.

After you download the .iso file, you can start installing TrueNAS!

This article describes verifying the .iso file, then installing TrueNAS using that file, and selecting the type of installation as either on physical hardware or a virtual machine (VM).
