Possibly. Depends if we want to use powershell commands in some of our code blocks. Our dvc highlighter extends on bash and doesn't highlight windows commands properly. If we want to use powershell commands, then we'd need to create or extend our dvc highlighter to work with powershell, not just bash. But if we just want to focus our code blocks on just using commands that work on both bash and powershell, we can probably just update our dvc highlighter to just check for $ or > in the beginning of a line.

It's a start.
