-\subsection{英文与数学字体}
+\subsection{数学字体选项}
+
+本模板定义了一个数学字体选项（\lstinline{math}），可选项有三个：
+\begin{enumerate}
+  \item \lstinline{math=cm}（默认），使用 \LaTeX{} 默认数学字体（推荐，无需声明）；
+  \item \lstinline{math=newtx}，使用 \lstinline{newtxmath} 设置数学字体（潜在问题比较多）。
+  \item \lstinline{math=mtpro2}，使用 \lstinline{mtpro2} 宏包设置数学字体，要求用户已经成功安装此宏包。
+\end{enumerate}
+
+\subsection{中文字体选项}
+模板提供中文字体选项 \lstinline{chinesefont}，可选项有
+\begin{enumerate}
+\item \lstinline{ctexfont}：默认选项，使用 \lstinline{ctex} 宏包根据系统自行选择字体，可能存在字体缺失的问题，更多内容参考 \lstinline{ctex} 宏包\href{https://ctan.org/pkg/ctex}{官方文档}\footnote{可以使用命令提示符，输入 \lstinline{texdoc ctex} 调出本地 \lstinline{ctex} 宏包文档}。
+\item \lstinline{founder}：方正字体选项，调用 \lstinline{ctex} 宏包并且使用 \lstinline{fontset=none} 选项，然后设置字体为方正四款免费字体，方正字体下载注意事项见后文。
+\item \lstinline{nofont}：调用 \lstinline{ctex} 宏包并且使用 \lstinline{fontset=none} 选项，不设定中文字体，用户可以自行设置中文字体，具体见后文。
+\end{enumerate}
+
+\noindent \textbf{注意：} 使用 \lstinline{founder} 选项或者 \lstinline{nofont} 时，必须使用 \hologo{XeLaTeX} 进行编译。
+
+\subsubsection{方正字体选项}
+由于使用 \lstinline{ctex} 宏包默认调用系统已有的字体，部分系统字体缺失严重，因此，用户希望能够使用其它字体，我们推荐使用方正字体。方正的{\songti 方正书宋}、{\heiti 方正黑体}、{\kaishu 方正楷体}、{\fangsong 方正仿宋}四款字体均可免费试用，且可用于商业用途。用户可以自行从\href{http://www.foundertype.com/}{方正字体官网}下载此四款字体，在下载的时候请\textbf{务必}注意选择 GBK 字符集，也可以使用 \href{https://www.latexstudio.net/}{\LaTeX{} 工作室}提供的\href{https://pan.baidu.com/s/1BgbQM7LoinY7m8yeP25Y7Q}{方正字体，提取码为：njy9} 进行安装。安装时，{\kaishu Win 10 用户请右键选择为全部用户安装，否则会找不到字体。}

+\subsubsection{其他中文字体}
+如果你想完全自定义字体\footnote{这里仍然以方正字体为例。}，你可以选择 \lstinline{chinesefont=nofont}，然后在导言区设置
+\begin{lstlisting}
+\setCJKmainfont[BoldFont={FZHei-B01},ItalicFont={FZKai-Z03}]{FZShuSong-Z01}

-本模板使用 \lstinline{newtxtext} 和 \lstinline{newtxmath} 分别设置全文的英文文本字体和数学字体。数学字体的效果如下：

 Default \LaTeX{} commands and environments are all the same in this template\footnote{To ensure the codes are replicatable. We recommend users pay more attention to the contents other than formats. This is the meaning of the existence of the template.}. We created four new commands:

+If you use \lstinline{newtx} fonts, type in:
 
-\section{Introduction}
-The content of introduction section.
+\begin{lstlisting}
+\documentclass[math=newtx]{elegantbook}
+\end{lstlisting}
 
-\section{Conclusion}
-The content of conclusion section.
 
-\bibliography{wpref}
+\subsection{Hyphens}
+Since the template uses \lstinline{newtx}, please pay attention to the hyphens. For instance,
+\begin{equation}
+\int_{R^q} f(x,y) dy.\emph{of\kern0pt f}
+\end{equation}
 
-\end{document}
+The corresponding code is: 
+\begin{lstlisting}
+\begin{equation}
+\int_{R^q} f(x,y) dy.\emph{of \kern0pt f}
+\end{equation}
 \end{lstlisting}
 
-\nocite{en1,en2}
-\bibliography{wpref}
+\subsection{Symbol Fonts}
+Feedback from ElegantBook users claims that error occurs when using our templates with  \lstinline{yhmath}, \lstinline{esvect} and other packages.
+\begin{lstlisting}
+LaTeX Error:
+Too many symbol fonts declared.
+\end{lstlisting}
+
+The reason is that the template redefines font for math so that no new math font is allowed to be added. To use \lstinline{yhmath} and/or \lstinline{esvect}, please locate \lstinline{yhmath} or \lstinline{esvect} in \lstinline{elegantpaper.cls}, uncomment corresponding related code.
