+ * @brief Functions for converting HTML to QTextDocument and vice versa
+ *
+ * Qt does contain its own functions for this, however they have some limitations. Some things that
+ * we want to support (e.g. kerning/spacing and font stretch) are not implemented in Qt's
+ * QTextHtmlExporter and QTextHtmlParser. Additionally, since these functions are not part of Qt's
+ * public API, and make many references to other parts of Qt that are not part of the public API,
+ * there is no way to subclass or extend their functionality without forking Qt as a whole.
+ *
+ * Therefore, it became necessary to write a custom class for the conversion so that we can
+ * ensure support for the features we need.
+ *
+ * If someone wishes to extend this class for more feature support, feel free to open a pull
+ * request. But this is NOT intended to be an exhaustive HTML implementation, and is primarily
+ * designed to store rich text in a standard format for the purpose of text formatting for video.
