This plugin provides a WYSIWYG (What You See Is What You Get) editor widget for typing your posts. It uses TinyMCE as the editor control.
The plugin currently provides two “theme” options for TinyMCE. The default is “Advanced”, which provides a fairly full-featured editor experience, with most of the options and controls you’re likely to need. The “Basic” theme is a much simpler, more stripped-down version for those who don’t like a lot of clutter in their editor’s tool bar.
The other option for this plugin is the URL to the TinyMCE instance to use. Unless you want to host your own copy of TinyMCE, you can ignore this. The default value is the CDN version of TinyMCE 4.0 hosted by CacheFly. This is free for public use and is probably much faster than your server anyway, so it will be the right choice for most people.
