Just to confirm: This works with all RR versions the wizard supports? Or if not, do we check for the required version range and fall back to linking to the manual setup guide?

[chargome]

No, thanks for raising, will add a guard!

[s1gr1d]

Looks good! Just some general questions: does this work when there is no entry.client.tsx? And why were all the fixtures deleted - don't we need them anymore?

@s1gr1d the entry.client file is always revealed in the wizard, if not it will throw earlier already. The fixtures got deleted bc we don't capture in the root file anymore so no more changes in there.
