## Installation

 1. Place entire /aitch-ref/ directory to the /wp-content/plugins/ directory

 3. Enter all possible site urls in the text box, each on a new line. Example could
    be https://wordpress.org/ , https://dev.wordpress.org/, http://dev.wordpress. Note–
    subdirectories to not currently work, so http://127.0.0.1/~wordpress/ would give
    you bad results
 4. _Important_ if SSL is used on site – each record needs an entry for ssl. For example,
    if your dev environment is http://dev.wordpress you will need to enter https://
    dev.wordpress as well even if it does not exist.
