The sudo command
In this document, sudo is used for any command that requires root privileges. You should always exercise caution when using sudo, as any changes can affect the entire system.

About the use of file paths in this document
In this document, all file paths are valid for Linux, UNIX, and similar operating systems (for example, /home/...). If you are using Microsoft Windows, you should use the equivalent Microsoft Windows paths (for example, C:\Users\...).

For example, in the following command, replace <install_dir> with your own directory name.
$ <install_dir>/bin/artemis create mybroker
