# Install ioctl Command line client
The most basic tool for a IoTeX developer to get started is ioctl: a command-line interface that can communicate with a IoTeX gateway node, allowing you to query and send actions to the blockchain. You can quickly download and install the latest release of ioctl typing the following command in a terminal window:
curl https://raw.githubusercontent.com/iotexproject/iotex-core/master/install-cli.sh | sh
ioctl is a powerful tool to interact with the IoTeX blockchain, and it also provides additional utility commands to be used locally: we will see some of the basic commands that you need to get started but you can also check out the full reference documentation.
