Then, create a Custom Integration (in your Ghost control panel under Settings > Advanced > Integrations > Add Custom Integration). Enter a name (whatever you want), then copy the full Admin API Key in your `SECRETS` file, mirroring the structure of SETTINGS:
The plugin hooks into Silver Bullet's [Share infrastructure](https://silverbullet.md/%F0%9F%94%8C_Share). Therefore to share a page as either a Ghost page or post, add a `$share` front matter key. For posts this should take the shape of:
---
$share:
- ghost:myblog:post:my-post-slug
---
And for pages:
---
$share:
- ghost:myblog:page:my-page-slug
---
Now, when you {[Share: Publish]} (Cmd-s/Ctrl-s) your post will automatically be created (as a draft) or updated if it already exists.
