Clarify Yarn not supporting prepare

[AlecRust]

It seems only Yarn v2 (and above) don't support prepare. Yarn Classic i.e. v1, does.

As such it seems "manual setup if using Yarn" should only be recommended if not using Yarn Classic.

In my testing with Yarn Classic, yarn husky init works fine, as does the prepare step in package.json.

To add to this discussion regarding Yarn - the documentation contradicts itself and is thus unhelpful.

On the manual setup (https://typicode.github.io/husky/how-to.html#manual-setup) with yarn selected, the first part suggests things to add to package.json and the first comment says Yarn doesn't support prepare script. The very next step is Run prepare once: yarn run prepare.

How does that make sense? What is the proper way to setup Husky with Yarn?

it's a mistake, yarn is enough to trigger the postinstall script there:

@typicode I think you're missing the point here.
Husky is still using prepare (in auto install and it also recommends it in manual install), while Yarn versions >+ 2.0 don't support prepare anymore. Husky should use postinstall instead.
