 \part{The template usage introduction of \textbf{Beautybook}}
 \chapter{A short introduction of \textbf{Beautybook}}
-Beauty \LaTeX{} series of templates is a book series made by me, an unknown little person. In fact, there are only two series, one is the custom book template \textbf{fancybook } , which is dedicated to the fresh and elegant style. (this has been changed permanently, because of my aesthetic problem, I prefer “Beauty”, forgive me!) , the other is my flagship product-\textbf{ Beautybook } ! About why they have such strange names? My answer is, originally I wanted to name it elegantboook, but there is already the famous elegantbook series, so I can only settle for the next best thing and name it a combination of a noun and a book with the same meaning of beauty, the Ancients Cloud: the book has its own Yan Ruyu, this is not, the beauty with books, is not beautiful! Therefore, this is the origin of \textbf{beauty book } !
 
-I am committed to creating a series of beautiful, elegant, simple template to facilitate the use of users and myself (mainly for their own, but can not stand the appreciation of everyone, I would like to introduce myself, please understand!) . Version changes frequently, please pay attention to version information, before starting to use templates, it is recommended to choose the latest official version! The latest test version will usually be released in the QQ Group, you can take it, after taking it is to stay at will.But unfortunately, I will be on July 5 in 2023  to stop maintenance and updates, so I can no longer solve the problem for you in the Q Group, Sorry!
+The Beauty\LaTeX{} collection is a series of templates authored by a humble, unknown individual. In fact, there are only two series, one is the custom book template \textbf{fancybook } , which is dedicated to the fresh and elegant style, the other is my flagship product-\textbf{ Beautybook } !  Why did I choose such an unusual name? My answer is, originally I wanted to name it elegantboook, but there is already the famous elegantbook template. Inspired by the old poem "There is a jade-like beauty waiting for you in the book", the template is named ``Beautybook", which means a beautiful woman in your arms and the fragrance of a book overflowing! Therefore, this is the origin of the name \textbf{Beautybook } !

-\section{Template Installation and Update}
 
-You will need to use this template by downloading it and compiling it. Only use it locally (within a folder) .
+\section{Installation and Maintenance of Template}
 
-\subsection{Use template online}
+There are two ways you can use this template. The first method is trivial that just download the zip of template from above channel, and then unzip and compile the main file in the archive (i.e. a file with a name like ``Beautybook-xx. tex"). The second way is uploading the zip of template to \texttt{overleaf} to comply.
 
-This template can be uploaded directly to overleaf for use, but note that you need to write \lstinline{math-font=plain} in the premble and compile with the XeLaTeX engine!
+Note that if you choose the second way,  you must write \lstinline{math-font=plain} in the premble of the main file!
+
+It is worth noting that when you download the template from CTAN, then the English version of it does not use any third-party fonts, so that one can be compiled using \texttt{pdflatex}. This is an exception to the rule under which all other files must be compiled using the \texttt{XeLaTeX} engine.
 
 \subsection{Local Installation}
 
-\textbf{Local Installation} use the following method: download the latest version from GitHub or QQ group, strictly need only class file \lstinline {.cls} and some folders. Then place the template files in your working directory and synchronously copy these folders: \texttt{fonts}, \texttt{stys}, \texttt{figures}, and \texttt{inner\_pics}, \texttt{frontmatter} to use. (If you are a chinese user, you can choose to copy the chinesefonts folder.) The advantage of this is that you can install \texttt{mtpro2} font to achieve a more elegant effect than if you were using it online. Of course, the choice is left to the users, and I won't comment here.

 \section{Language Mode}
 
-This template contains two basic locales, \lstinline{Beautybook-V6.1.cls} in Chinese and \lstinline{Beautybook-V6.1-EN.cls} in English. Changing the locales will change the leading words (include figures, tables) of the chart title, the structure of the article (e.g. table of contents, references, etc.), and the leading words in the context of the theorem (e.g. Theorem, lemma, etc.). The different language modes are enabled as follows:

Changing the locales alters the headings (including figures and tables) of the chart title, the article formatting (such as table of contents and references), and the language used for theorem contexts (such as Theorem, Lemma, etc.). You can switch between these language modes using the following instructions in the top of the premble:
