As we build new features in the config-batch command, we define the
plaintext protocol with line-by-line output and responses. To think to the
future, we make sure that the protocol has a clear way to respond to an
unknown command or an unknown version of that command.

As some commands will allow the final argument to contain spaces or even be
able to parse "\ " as a non-split token, we only provide the remaining line
as data.

 DESCRIPTION
 -----------
-TODO
+Tools frequently need to change their behavior based on values stored in
+Git's configuration files. These files may have complicated conditions
+for including extra files, so it is difficult to produce an independent
+parser. To avoid executing multiple processes to discover or modify
+multiple configuration values, the `git config-batch` command allows a
+single process to handle multiple requests using a machine-parseable
+interface across `stdin` and `stdout`.
+
+PROTOCOL
+--------
+By default, the protocol uses line feeds (`LF`) to signal the end of a
Characters are typefaced as placeholders: _LF_
+command over `stdin` or a response over `stdout`.
+
+The protocol will be extended in the future, and consumers should be
+resilient to older Git versions not understanding the latest command
+set. Thus, if the Git version includes the `git config-batch` builtin
+but doesn't understand an input command, it will return a single line
+response:
+
+```
+unknown_command LF> +```
