-Before Nu version 0.67, Nu [used to](https://www.nushell.sh/blog/2022-08-16-nushell-0_67.html#windows-cmd-exe-changes-rgwood) use CMD.EXE to launch external commands, which meant that the above builtins could be run as an `^external` command. As of version 0.67, however, Nu no longer uses CMD.EXE to launch externals, meaning the above builtins cannot be run from within Nu, except for `ASSOC`, `CLS`, `ECHO`, `FTYPE`, `MKLINK`, `PAUSE`, `START`, `VER`, and `VOL`, which are explicitly allowed to be interpreted by CMD if no executable by that name exists.
+## Forwarded CMD.EXE commands
+
+Nu accepts and runs *some* of CMD.EXE's internal commands through `cmd.exe`.
+
+The internal commands are: `ASSOC`, `CLS`, `ECHO`, `FTYPE`, `MKLINK`, `PAUSE`, `START`, `VER`, `VOL`
+
+These internal commands take precedence over external commands.
+
+For example, with a `ver.bat` file in the current working directory, executing `^ver` executes CMD.EXE's internal `VER` command, *NOT* the `ver.bat` file.
+
+Executing `./ver` or `ver.bat` *will* execute the local bat file though.
