LGTM

The c3 template has not yet been updated for 0.3. however the ON version is not pin to 0.2.x in the last c3 release (I submited a PR that got merged after the last release).

I'm not sure what's the best time to merge this PR. Either now or once the c3 template is updated.

I'll let you decide

Thanks 🙂

The part of the guide I've updated is under Existing Next.js apps so it is actually unrelated to C3, so I would say the sooner we merge this the better 🙂 (I linked this PR with the workers-sdk one just because those are loosely related)

So I'd just wait for a PCX review and then merge 🙂

@vicb the video tutorial is also outdated... we should probably do something about that too... I think we can either put a warning callout there saying that it is slightly outdated and maybe also point out what changed since the video was made or remove the video tutorial completely.

By far I prefer the latter as the former feels very unpolished and more costly to maintain to me, what do you think? do you have a preference here?

@megaconfidence as mentioned above (and discussed with Vic offline) we're removing your video tutorial, sorry about that 😓, maybe we can work together to get an updated version of it up? 😄
