Should we still keep all list of commands here? 🤔

I like the new one, I would remove this 👍

Removing, let's see how everyone else finds it :)

Thank you for your pull request! The most important CI builds succeeded, we’ll review the pull request soon.

[misterdev]

Well done! Would be nice to have a summary of the other packages like webpack-scaffold, generators and util that aren't mentioned here. What do you think? :)

@anshumanv Thanks for your update.

I labeled the Pull Request so reviewers will review it again.

@misterdev Please review the new changes.

@misterdev since (utils, generators, webpack-scaffold) packages are just helpers to other packages and don't have a real command so I'm not sure if it's the best idea to list them in the commands section. WDYT? :)

[misterdev]

Yeah, I would make another list e.g. "Packages" after the "Commands" section :)
Another idea I like is to have a structure like this:

Packages
We organize webpack CLI as a multi-package repository. Every command has a dedicated subfolder in the packages Folder [...]

• Commands
  Supporting developers is an important task for webpack CLI. Thus, webpack CLI provides different
  commands for many common tasks
  ... list of all commands with description
• Utilities
  ... list of all other packages with descriptions

IMO, having a complete overview of the repository in the REAME is something desirable

PS: I can work on this, in case it is not in the scope of this PR or you have something else to do :)

Sounds good @misterdev, just a trivial change. ✨
