When you run nRF Util for the first time, it automatically installs the latest version of the nRF Util core module.
Tip
If you are configuring a CI production environment, you can work around this by setting the NRFUTIL_BOOTSTRAP_TARBALL_PATH environment variable before you run nRF Util.
The nRF Util version you download does not come with any pre-installed commands. Therefore, the first time you use nRF Util, you need to search for available commands and install each of them. For example, run the following command to install the nrfutil completion command:
nrfutil install completion
