Basic instructions

This is the minimal configuration for getting TinyMCE to replace a textarea.

<!-- Place inside the <head> of your HTML -->
<script type="text/javascript" src="<your installation path>/tinymce/tinymce.min.js"></script>
<script type="text/javascript">
    selector: "textarea"

<!-- Place this in the body of the page content -->
<form method="post">

Any configuration is a derivative of this basic principle.

Check out the configuration options to customize your installation.
