Looks good, but :)

• Markdown in the console output:

$ paket add --help
Paket version 0.17.19.0
# paket add

Adds a new package to your [`paket.dependencies` file](dependencies-file.html).

    [lang=batchfile]
    $ paket add nuget PACKAGENAME [version VERSION] [--interactive] [--force] [--hard]

• paket without parameters still has that strange commands-on-top, parameters-at-the-bottom layout.

But we're getting there!

[forki]

yeah now we need ideas how to improve this ;-)

[agross]

Does your markdown lib support rendering to text?

[forki]

@tpetricek's FSharp.Formatting uses Razor for the output. So probably yes.

[forki]

maybe we just split the stuff into cmd text and "additional" docs.

[tpetricek]

F# Formatting doesn't currently have text output, but it sounds like a fun project. I'm sure we could find a contributor for that. It's just a matter of walking over the AST

[forki]

At the moment I'm trying to come up with a simpler solution which doesn't need to reference FSharp.Formatting.

It's already progress. We will improve along the way.
