-__Important:__ Crawling with PhantomJS is currently only possible as an advanced option in Hyphe. Do not bother with this section except for advanced use or development.

-Hyphe ships with a compiled binary of PhantomJS-2.0 for Ubuntu, unfortunately it is not cross-compatible with other distributions: so when on CentOS or Debian, you should compile your own from sources.

-Note that PhantomJS 1.9.7 is easily downloadable as binary, altough it uses a very outdated version of WebKit and PhantomJS 2+ is required to handle modern websites such as Facebook.
