 If you're on WSL, follow [these steps](https://github.com/microsoft/WSL/issues/3161#issuecomment-451863149). For more background, see [this guide](https://240dc.com/wsl2-add-a-local-ssl-certificate-with-mkcert/), but rather execute the commands as shown in the first link. It's a bit tedious, but you will get there.
 
+Playwright tests do not need those certificates. The local and CI test setup starts Vite over plain `http` because the Office APIs are mocked in that scenario.

 ### Debug

 ## Test production-like environment
 
 All you have to do is sideload the `manifest.prod.xml` instead of the manifest used for local development `manifest.xml`. To do so, copy the `manifest.prod.xml` to some `tmp/` folder that you have added to the PowerPoint Trust Center (see above) and rename the file to `manifest.xml` such that PowerPoint recognizes it.

 The production manifest has URLs configured to point to the site hosted on GitHub Pages. This way, you can see if everything works fine. All we ship to the PowerPoint Marketplace is the Manifest file in the end.
