Jekyll has a rule that any directory not starting with `_` will be copied as-is to the `_site` output. Hugo keeps all static content under `static`. You should therefore move it all there.
Hugo can read your configuration as JSON, YAML or TOML. Hugo supports parameters custom configuration too. Refer to the [Hugo configuration documentation](/overview/configuration/) for details.
## Set your configuration publish folder to `_site`
The default is for Jekyll to publish to `_site` and for Hugo to publish to `public`. If, like me, you have [`_site` mapped to a git submodule on the `gh-pages` branch](http://blog.blindgaenger.net/generate_github_pages_in_a_submodule.html), you'll want to do one of two alternatives:
1. Change your submodule to point to map `gh-pages` to public instead of `_site` (recommended).
That's the bulk of the work right here. The documentation is your friend. You should refer to [Jekyll's template documentation](http://jekyllrb.com/docs/templates/) if you need to refresh your memory on how you built your blog and [Hugo's template](/layout/templates/) to learn Hugo's way.
As an example, I was using a custom [`image_tag`](https://github.com/alexandre-normand/alexandre-normand/blob/74bb12036a71334fdb7dba84e073382fc06908ec/_plugins/image_tag.rb) plugin to generate figures with caption when running Jekyll. As I read about shortcodes, I found Hugo had a nice built-in shortcode that does exactly the same thing.

Depending on the amount of customization that was done with each post with Jekyll, this step will require more or less effort. There are no hard and fast rules here except that `hugo server --watch` is your friend. Test your changes and fix errors as needed.
