@samuelFain @dorschw anything more we want to add here at the moment?

@Shellyber I think we said we want to align the -help feature with these docs as well no?

@Shellyber
I think it looks a lot better, the separation between of the installation and environment setup is very clear.
About docs/demisto-sdk-docker.md, is it corresponding with a page in the documentation as well? Do we plan to add more markdowns to the docs folder?

Yes. I'll add the demisto-sdk flags as well to the docs here and afterward to the official docs site as well.

For the moment, the docker article does not exist on the official docs site - right now it is referred to xsoar.pan.dev page which won't be longer accessible. So I'm adding it here in the meantime.
Once I'll do the work with the docs team, we can add the article directly there, and reference from here.
But I think it is a good place to keep this article as well.
Regarding more docs, not at the moment, but it is good to have it anyway.
