hugo new site quickstart
git submodule add https://github.com/mismith0227/hugo_theme_pickles themes/pickles;
echo 'theme = "pickles"' >> config.toml
hugo new posts/my-first-post.md
hugo server -D
Now it works well in the local live server.
But when I generate the static files with hugo, the newly created article my-first-post disapeared!
