I've read through it and it looks good.

I'm gonna take a look at why playwright suddenly isn't working later today though

[phil-scott-78]

Opps, looks like commit 8ce40ba might be the cause. I'm thinking that the change went from an explicit install to a restore, but without a tool-manifest it doesn't know to install playwright hence the error.

@phil-scott-78 Ah, I see. I had to remove it since it errored when installing since it was specified in the manifest. Any suggestions on how to move forward here?

[phil-scott-78]

I'm thinking dotnet tool saw the dotnet-tools.json in the root of the repository and put the entry for microsoft.playwright.cli there. But we are running these commands from a child folder. So, when we are restoring from the docs folder perhaps it isn't finding it? I'm on my phone so I can test, but perhaps a dotnet-tools.json file in the docs folder is needed with playwright installed there?

I think I got the build fixed with #667. After that's reviewed and (possibly) merged think we could rebase? Content looks good, just gotta make sure it gets deployed :-)
