+\addcontentsline{toc}{section}{Before you start}
+
+In order to use the toolkit, you need to:
+\begin{itemize}
+     \item install TeX Live or MikTeX of the latest possible version, and to make sure that \texttt{projlib} is correctly installed in your \TeX{} system.
+     \item be familiar with the basic usage of \LaTeX{}, and to know how to compile your documents with \hologo{pdfLaTeX}, \hologo{XeLaTeX} or \hologo{LuaLaTeX}.
+\end{itemize}
+
+\section{Introduction}
+
+The name \ProjLib{} can be regarded as the abbreviation of \emph{Project Library} in English or \emph{Projet Libre} in French (the author prefers the French interpretation). Its main purpose is to provide multi-language support and theorem-like environments with clever references. In addition, some additional features are provided, such as the enhanced author block, draft marks, mathematical symbols and shortcuts, etc.
+
+The \ProjLib{} toolkit is composed of the main package \ProjLibPackage{} and a series of components whose names begin with the abbreviation "PJL". You can learn how to use it through the usage examples in the next section.

+If you find it a little complicated, don't worry. Let's now look at this example piece by piece.
 
-\subsection{Options}
+\clearpage
+\subsubsection{Initialization}
+
+\begin{code}
+\documentclass{article}
+\usepackage[a4paper,margin=.75in]{geometry}
+\usepackage[hidelinks]{hyperref}
+\usepackage[palatino]{ProjLib}
+\end{code}
+
+In standard classes, one usually only need to configure the page size, hyperlinks and load \ProjLibPackage{} before actually start writing the document. The font option \texttt{palatino} of \ProjLibPackage{} is used here. For all available options of \ProjLibPackage{}, please refer to the next section.
+
+Of course, you can also use the document class \textsf{amsart}, the configurations are the same.
+
+\subsubsection{Set the language}
+
+\begin{code}
+\UseLanguage{French}
+\end{code}
+
+This line indicates that French will be used in the document (by the way, if only English appears in your article, then there is no need to set the language). You can also switch the language in the same way later in the middle of the text. Supported languages include Simplified Chinese, Traditional Chinese, Japanese, English, French, German, Spanish, Portuguese, Brazilian Portuguese and Russian\footnote{However, you need to add the encoding support and fonts of the corresponding language by yourself. For example, for Chinese, you may need to load the \textsf{ctex} package and set the fonts. As a sidenote, you can try the author's document classes \textsf{einfart} or \textsf{lebhart}, in which the corresponding settings have been completed. For the details, run \lstinline|texdoc minimalist| or \lstinline|texdoc colorist| in the command line.}.
+
+For detailed description of this command and more related commands, please refer to the section on the multi-language support.
+
+\subsubsection{Title and author information}
+
+\begin{code}
+\title{(*\meta{title}*)}
+\author{(*\meta{author}*)}
+\date{\PLdate{2022-04-01}}
+\end{code}
+
+This part is the title and author information block. The example shows the most basic usage, but in fact, you can also write:
+\begin{code}
+\author{(*\meta{author 1}*)}
+\address{(*\meta{address 1}*)}
+\email{(*\meta{email 1}*)}
+\author{(*\meta{author 2}*)}
+\address{(*\meta{address 2}*)}
+\email{(*\meta{email 2}*)}
+...
+\end{code}
+
+In addition, if the \AmS{} simulation is enabled\footnote{This is achieved by the module \PJLamssim{}. Since this module modifies some internal macros of \LaTeX{}, it may conflict with some packages or document classes, and thus it is not enabled by default.}, then you can also write in the \AmS{} fashion (the original way still works). In this case, the line that introduces \ProjLibPackage{} should be written as:
+\begin{code}
+\usepackage[amsfashion,palatino]{ProjLib}
+\end{code}
+And correspondingly, you will also be able to use these macros:
+\begin{code}
+\dedicatory{(*\meta{dedicatory}*)}
+\subjclass{*****}
+\keywords{(*\meta{keywords}*)}
+\end{code}
+In addition, you can also write the abstract before \lstinline|\maketitle|, as the way required in the \AmS{} classes:
+\begin{code}
+\begin{abstract}
+    (*\meta{abstract text}*)
+\end{abstract}
+\maketitle
+\end{code}
+
+\subsubsection{Draft marks}
+\begin{code}
+\dnf<(*\meta{some hint}*)>
+\end{code}
+When you have some places that have not yet been finished yet, you can mark them with this command, which is especially useful during the draft stage.
+
+\subsubsection{Theorem-like environments}
+\begin{code}
+\begin{theorem}\label{thm:abc}
+    Ceci est un théorème.
+\end{theorem}
+Référence du théorème: \cref{thm:abc}
+\end{code}
+
+Commonly used theorem-like environments have been pre-defined. Also, when referencing a theorem-like environment, it is recommended to use \lstinline|\cref{|\meta{label}\texttt{\}} --- in this way, there is no need to explicitly write down the name of the corresponding environment every time.

-If \PJLamssim{} is loaded, then one can adopt the \AmS{} writing style in the document (of course, the original way is also valid, so always adding the option \texttt{amssim} usually does not cause problems). This way, the line that introduces \ProjLibPackage{} should be written as:
-\begin{code}
-\usepackage[amssim,palatino]{ProjLib}
-\end{code}
-
-\clearpage
-\subsection{The \texorpdfstring{\AmS{}}{AMS} classes}
-
-In \AmS{} classes, one usually only need to configure the page size, hyperlinks and load \ProjLibPackage{} before actually start writing the document. Below is a complete example.
-\begin{code}
-\documentclass{amsart}
-\usepackage[a4paper,margin=.75in]{geometry}
-\usepackage[hidelinks]{hyperref}
-\usepackage[palatino]{ProjLib} % Load the toolkit and use font Palatino
-
-\UseLanguage{French} % Use French from here
