# Simple Daemon
Let's start with our "daemon". Create the file
cmd/hcd/main.go. This will be
hellochain daemon command. For now we will rely on
starter to bundle
things up, but we will come back later to add our own
when it's ready.
./cmd/hcd/main.go should look like this. We will use it to start and run
The Cosmos SDK uses [cobra])(https://github.com/spf13/cobra) for building and running CLI commands.
Next we will create the cli for interacting with the modules and parts of the chain. Start by creating the file
cmd/hccli/main.go. We will be relying on the start package for now, until we come back to add the module you will create in this tutorial.
Next we will create a Makefile for building and installing the package.
