 Relevant, editable content is organized in the following directories and files:
 
-- [_config.yml](https://github.com/oceanhackweek/oceanhackweek.github.io/blob/master/_config.yml): core Jekyll site configuration, including some banner/header/footer text and urls
-- [jekyll-spectral-theme/_includes](https://github.com/oceanhackweek/oceanhackweek.github.io/tree/master/jekyll-spectral-theme/_includes) directory: front page content, broken up into sections, one markdown file per section.
-  - The layout templates for sections and section order are controlled by [jekyll-spectral-theme/_layouts/default.html](https://github.com/oceanhackweek/oceanhackweek.github.io/blob/master/jekyll-spectral-theme/_layouts/default.html)
-  - Each section specifies a template for its layout, where the templates available are found in [jekyll-spectral-theme/_layouts](https://github.com/oceanhackweek/oceanhackweek.github.io/tree/master/jekyll-spectral-theme/_layouts)
-  - Section two ("Information for Applicants") is a special beast. While [jekyll-spectral-theme/_includes/section-02.html](https://github.com/oceanhackweek/oceanhackweek.github.io/blob/master/jekyll-spectral-theme/_includes/section-two.html) orchestrates it, the directives there point to content to be grabbed from tags `title` and `description` in [_pages/01-applicants.md](https://github.com/oceanhackweek/oceanhackweek.github.io/blob/master/_pages/01-applicants.md)
-- [_pages](https://github.com/oceanhackweek/oceanhackweek.github.io/tree/master/_pages): content for extra pages, including all the pages accessible via the drop-down menu on the upper right of the page.
-  - The destination page file name (what a user sees) is *not* the source markdown file name on the repository; instead, the destination file name is found in the `permalink` tag within the markdown file. For example, for [_pages/01-applicants.md](https://github.com/oceanhackweek/oceanhackweek.github.io/blob/master/_pages/01-applicants.md), the destination file name is [applicant-info.html](https://oceanhackweek.github.io/applicant-info.html)

 Note that apparently any Markdown file dropped at the root level of the repository, or in the `_pages` directory (or possibly anywhere else?), will be automatically added to the Menu drop down; except ones with names starting with the `_` character.
