Is it possible to build a Ghost site using the Lyra theme and deploy it on Netlify through github?

Is it possible to build a static version of my Ghost site which is using the Lyra theme and deploy it on Netlify through GitHub??

I got stuck on what command I would use to build my Ghost site.

See attached image:

I think I’ve misunderstood how Ghost works slightly. So the typical Ghost themes are not static sites I’m now beginning to understand.

Ghost do not generate static site. It has 3 different part, At core there is a JSON API. Then to manage content there is the admin app. And a front-end layer.
The themes are used for this front-end layer.

Ghost site can not be hosted on github or netlify because A Nodejs server is required to run Ghost.

You can read more about Ghost and how it’s work here.

If you wish you can use Ghost as a headless CMS. And use a static site generator to generate static site consuming data from the Ghost via API.
