hcadmin init <agent-id-string>

This command initializes the Holochain environment, and must be run before you install or run chains. You must provide a unique agent identification, usually an e-mail, as an argument to this command.

This command initializes the system with a default identity and generates default public/private keys for interacting with other networked peers. You provide a single string of identifying information which will be provided to the application as your agent_name. This is often an email address.

This command creates a ~/.holochain directory (by default, which you can override with the --path flag) where all your holochain data will be stored.
