+Usage: atmos terraform [global options] <subcommand> [args]
+
+The available commands for execution are listed below.
+The primary workflow commands are given first, followed by
+less common or more advanced commands.
+
+Atmos commands:
+  generate backend          	Command generates a backend config file for an 'atmos' component in a stack
+  generate backends          	Command generates backend config files for all 'atmos' components in all stacks
+  generate varfile          	Command generates a varfile for an 'atmos' component in a stack
+  generate varfiles          	Command generates varfiles for all 'atmos' components in all stacks
+  shell          		Command configures an environment for an 'atmos' component in a stack and starts a new shell allowing executing all native terraform commands inside the shell without using atmos-specific arguments and flags
+  double-dash '--'          	Can be used to signify the end of the options for Atmos and the start of the additional native arguments and flags for the 'terraform' commands. For example: atmos terraform plan <component> -s <stack> -- -refresh=false -lock=false
+  '--append-user-agent'         Flag sets the TF_APPEND_USER_AGENT environment variable to customize the User-Agent string in Terraform provider requests. Example: 'Atmos/0.0.1 (Cloud Posse; +https://atmos.tools)'. If not specified, defaults to 'atmos 0.0.1'
