The language is quite primitive, even simpler than cmd.exe. Builtin
commands are borrowed from either bash (like ls, mkdir or cd) or Windows
cmd (like ver or vol, or using "drive letters" like fs0:). Yet the most
important features like output redirection are supported. What set me
off at the beginning: The output redirection characters > < | need to be

At least you found the help command. The version I have shows as last
line of the help text (scrolling by) to run "help -b" to enable the
pager. If yours does not, maybe it is supported anyway? The pager does
not allow scrolling upwards like "less" does, but it is good enough to
read help pages in the system itself.
If you need more "less" than the builtin pager and have at least one
writable filesystem (e.g. the EFI system partition or a FAT32 partition
on an USB key) you can also do:
help > help.txt
Cursor keys work in the editor as expected.
Help for the editor with Ctrl+E (shown in the last line for me), exit
the editor with F3.
