**footnotes** aims to be the all-in-one solution for displaying an
automatically-generated list of references on your Page or Post. The Plugin
ships with a set of defaults while also empowering you to control how your
footnotes will be displayed.

**footnotes** gives you the ability to display well-formatted footnotes on your
WordPress Pages and Posts — those footnotes we know from offline publishing.

Featured on [wpmudev][wpmudev] — cheers for the review, folks!

## Features

This Plugin provides:

* fully customizable footnote start and end shortcodes;
* stylable tooltips supporting hyperlinks and dedicated text;
* a responsive 'reference container', with customisable positioning;
* a wide choice of different numbering styles;
* a freely-configurable and optional backlink symbol;
* footnote appearance customisation via dashboard settings and custom CSS style
  rules; and
* editor buttons for easily adding shortcode tags.

## Getting Started

1. Read the [contributing guidelines][contributing];
1. clone this repository (`git clone git@github.com:markcheret/footnotes.git`):
    * we recommend that you use [VVV][vvv] for your local testing environment.
1. install [Composer][composer] and [NPM][npm]; and
1. install all dependencies (`composer install`):
    * you will have to install `php-mbstring` manually if you do not already
      have it.

## Deploying

Automated release deployments will be introduced soon.

### Building

1. Run `_tools/build-stylesheets.sh -c` to concatenate stylesheets;
1. manually minify the output files in `css/tmp/`, saving them as `.min.css` files:
    * the intention is to replace this with automated minification, meaning that
    all of these steps can be rolled into a single `build` command.
1. run `_tools/build-stylesheets.sh -d` to deploy the minified files to `dist/`:
    * **this will delete any existing `dist/` folder!**
1. run `composer run build` to move over the remaining files to `dist/`:
    * currently, the files to include in a distribution are hard-coded in
      `_tools/build.sh`; but
    * the intention is to replace this with a proper parsing of the `.distignore`
      file
  
### Releasing

1. Ensure that you have configured your Git config. with SVN credentials;
1. run the above [build](#building) commands; and
1. run `composer run release` and follow the prompts.
