+## Boot Command
+
+The `boot_command` specifies the keys to type when the virtual machine is first booted. This command is typed after `boot_wait`.
+
+As documented above, the `boot_command` is an array of strings. The
+strings are all typed in sequence. It is an array only to improve readability
+within the template.
+
+The boot command is "typed" character for character using the `prltype` (part

+command connected to the machine, simulating a human actually typing the
+keyboard. There are a set of special keys available. If these are in your
+boot command, they will be replaced by the proper key:
+
+* `<enter>` and `<return>` - Simulates an actual "enter" or "return" keypress.
+
+* `<esc>` - Simulates pressing the escape key.
+
+* `<tab>` - Simulates pressing the tab key.
+
+* `<wait>` `<wait5>` `<wait10>` - Adds a 1, 5 or 10 second pause before sending
+  any additional keys. This is useful if you have to generally wait for the UI
+  to update before typing more.
+
+In addition to the special keys, each command to type is treated as a

 define extra calls to `prlctl` to perform.
