All interaction with 9 Packer is done via the `packer` tool. Like many other command-line tools, 10 the `packer` tool takes a subcommand to execute, and that subcommand may 11 have additional options as well. Subcommands are executed with 12 `packer SUBCOMMAND`, where "SUBCOMMAND" is obviously the actual command you wish 13 to execute. 14 15 If you run `packer` by itself, help will be displayed showing all available 16 subcommands and a brief synopsis of what they do. In addition to this, you can 17 run any `packer` command with the `-h` flag to output more detailed help for 18 a specific subcommand. 19 20 In addition to the documentation available on the command-line, each command 21 is documented on this website. You can find the documentation for a specific 22 subcommand using the navigation to the left.
