# Overview

The cio command-line is used to manage logical resources, such as volumes, snapshots and profiles. This interface is generally used by developers to directly manage their own resourcs using the cio command. The cio command has many subcommands, such as cio info, cio volume, cio snapshot, etc.

Running cio by itself displays help showing all available subcommands. In addition, you can run any command with the --help flag to output help information. For example, try running cio volume --help. This outputs a one sentence usage info and lists all options the command accepts. Details on various cio commands are available in the left navigational section of this site.

To simplify the command-line for developers, the actions of subcommands have aliases, e.g. list and ls both list resources. create and add are aliases, delete, remove and rm all remove resources.
