There is interesting case, if you use webpack@4 you can install this plugin just using another version

[alexander-akait]

webpack@5 uses the latest version of this plugin

[antonk52]

Yep, with webpack v4 it was a common practice to install this plugin explicitly in order to use the latest version. Since currently the latest webpack version is 5 I do not think this needs to be addressed in the readme. Though I am fine with either way. If you can think of a better way to phrase this I am happy to make the idea more transparent for the users.

Maybe we add this only for webpack@5? Because currently it can be some misleading for v4
