-\chapter{旁注}
-在 3.08 版本,我们加入了旁注(边注)等设置以及 \lstinline{\elegantpar} 命令,不过目前处于测试阶段。如果你想整个文档都加入旁注,一般的方法是,重新设置旁注的大小。本模板加入了一个旁注选项 \lstinline{marginpar},如果加入旁注 \lstinline{marginpar=margintrue},则会减少版芯两边的宽度(减少至 1.5cm),如果不加入旁注 \lstinline{marginpar=marginfalse}(默认),则维持两边距离不变。旁注选项仅对 \lstinline{device=normal} 试用,pad 模式并不支持。
-
-旁注命令可以使用 \LaTeX{} 自带的 \lstinline{\marginpar} 命令或者 \lstinline{marginnote}  宏包的  \lstinline{\marginnote}  命令,旁注的使用,请参考维基百科:\href{https://en.wikibooks.org/wiki/LaTeX/Footnotes_and_Margin_Notes#Margin_Notes}{旁注}或者 \LaTeX {}书籍。
-
-本模板还添加了一个 \lstinline{\elegantpar} 命令,需要注意的是,由于这个命令使用了 TikZ 中的层叠效果(overlay),所以为了得到正确的旁注显示,你需要多次编译(3 次)。\lstinline{\elegantpar} 命令的效果如下。

+\section{Margin Notes}
+In 3.08, we introduced \lstinline{marginpar=margintrue} and \lstinline{\elegantpar} (Beta) with piles of bugs. Hence we decide to remove them in 3.09 and will suspend the options till revolutionary optimization. Sorry for all the bugs! However, we retain the option \lstinline{marginpar} for users to get margin motes by activating \lstinline{marginpar=margintrue} and using \lstinline{\marginpar} or \lstinline{marginnote} packages.
 
+\begin{remark}
+
+Note that text and equation are both available in the margin notes.
+\begin{lstlisting}
+% text
+\marginpar{margin paragraph text}
+
+% equation
+\marginpar{
+\begin{equation}
+	a^2 + b^2 = c^2
+\end{equation}
+}
+\end{lstlisting}
+
+For tables and figures, note that floating environment is not allowed. You have to use \lstinline{includegraphics} or \lstinline{table} and use \lstinline{\captionof} to name it. To get centralized figures or tables, use \lstinline{\centerline} or \lstinline{center}. To learn more, please refer to \href{https://tex.stackexchange.com/questions/5583/caption-of-figure-in-marginpar-and-caption-of-wrapfigure-in-margin}{Caption of Figure in Marginpar}.

+\section{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}
+
+The corresponding code is: 
+\begin{lstlisting}
+\begin{equation}
+\int_{R^q} f(x,y) dy.\emph{of \kern0pt f}
+\end{equation}
+\end{lstlisting}
+
+\section{Symbol Fonts}
+Feedback from some 3.08 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{elegantbook.cls}, uncomment corresponding related code.
+\begin{lstlisting}

-\chapter{Margin Notes}
-For version 3.08, we introduce margin note option and \lstinline{\elegantpar} (Beta). In this template, margin note option \lstinline{marginpar} is included. If \lstinline{marginpar=margintrue}, the width of both sides will reduce at least 1.5cm. If \lstinline{marginpar=marginfalse}, the width of sides will remain unchanged. Margin note option works under \lstinline{device=normal} only.
 
-Margin note option can be activated using \lstinline{\marginpar} built in \LaTeX{} or \lstinline{\marginnote} command in \lstinline{marginnote}. For more information, refer to \href{https://en.wikibooks.org/wiki/LaTeX/Footnotes_and_Margin_Notes#Margin_Notes}{Margin Notes} or \LaTeX{} books.

-\lstinline{\elegantpar} is introduced in this version. Note that TikZ overlay is used in this command, hence you have to compile three times to get the right display effect.
