To update from a GoogleDoc and save the output as html, use the claat tool.

eg.

claat-linux-amd64 export 1fDRVc23lN8wi65TuxrLLhIGNG1huqCi7fHnv_9vD-oc

The above should only be done while actively editing the Google Doc.

Once the document is ready for initial publication, it needs to be exported as markdown, again using the claat tool:

claat-linux-amd64 export -f md -o src 1fDRVc23lN8wi65TuxrLLhIGNG1huqCi7fHnv_9vD-oc

and the markdown and associated files can then be committed into this git repo. This is a one time step and from this point on ward, all changes to the codelab content need to be made in the markdown document and then the static html exported using the claat tool:

claat-linux-amd64 export -f cm_template.html src/your-first-flutter-app-to-appstore/index.md

The -f flag above is required because we need to use a slightly customised version of the standard claat html template to allow us to use Plausible rather the GA for analytics.
