When you run blake build the content is generated into public
directory. Markdown files are rendered into HTML using templates and
files from static directory are copied into public without any change.
You can deploy the content of public directory to your website.
Install gh_pages package and run following command.
gh_pages public
This creates branch gh-pages if it does not exist and copies files from public
dir into this branch. Finally, it pushes the changes to your remote repository.
You will also need to configure Github Pages in your repository for this to work.
Netlify will require custom build script that is not yet implemented. It is planned, although it is not a priority.
