+- title: 词法分析器模块
+  content: |
+    词法分析器模块负责将源代码转换为一系列标记（tokens）。它识别语言的基本元素，如标识符、关键字、运算符和字面量。
+    <!-- `['OPERATOR', 'IDENTIFIER', 'SEPARATOR', 'SEPARATOR', 'CONTROL', 'IDENTIFIER', 'OPERATOR', 'INTEGER', 'SEPARATOR', 'IDENTIFIER', 'SEPARATOR', 'IDENTIFIER', 'OPERATOR', 'IDENTIFIER', 'SEPARATOR', 'IDENTIFIER', 'SEPARATOR', 'EOF']` -->
+- title: 语法分析器模块
+  content: |
+    语法分析器模块接收词法分析器模块生成的标记序列，并将其转换为抽象语法树（AST）。AST是一种类似树状的数据结构，以更接近编程语言的语法结构的方式表示源代码。
+- title: 内置类型模块
+  content: |
+    此模块定义了Psi语言的内置类型，如列表和字典。它提供了用于创建和操作这些类型实例的函数。
+- title: 错误处理模块
+  content: |
+    此模块提供了在运行时捕获和处理错误的机制。它定义了一组异常类和用于抛出和捕获这些异常的函数。
+- title: 执行环境模块
+  content: |
+    此模块定义了Psi语言的执行环境，包括变量的作用域和生命周期。它提供了用于在执行环境中定义和查找变量的函数。
+- title: 解释器模块
+  content: |
+    此模块的主要任务是遍历AST并在执行环境中执行相应的操作。

+\maketitle
+
+\begin{abstract}
+    Psi is a new programming language designed with simplicity, flexibility, and performance in mind. It provides a clean and intuitive syntax that is easy to read and write, making it an excellent choice for both beginners and experienced programmers.
+\end{abstract}
+
+\section{Introduction}
+This section introduces the Psi CLI language and its features.
+
+\section{Features}
+This section describes the key features of the Psi CLI language.
+
+\subsection{Lexer Module}
+The lexer module is responsible for converting source code into a sequence of tokens.
+It recognizes the basic elements of the language such as identifiers, keywords, operators, and literals.
+
+\begin{table}[htbp]
+    \caption{Code Tokens and Corresponding Meanings}
+    \label{table:code_tokens}
+    \centering
+    \begin{tabular}{@{} c|c @{}}
+        \toprule
+        \textbf{Token} & \textbf{Meaning} \\
+        \midrule
+        list           & TYPE \\
+        colors         & IDENTIFIER \\
+        =              & EQUALS \\
+        red            & IDENTIFIER \\
+        ,              & COMMA \\
+        blue           & IDENTIFIER \\
+        ,              & COMMA \\
+        green          & IDENTIFIER \\
+        \bottomrule
+    \end{tabular}
+\end{table}
+
+\subsection{Parser Module}
+The parser module converts the token sequence into an abstract syntax tree (AST).
+
+\subsection{Built-in Types Module}
+The built-in types module defines the built-in types of the Psi language, such as lists and dictionaries.
+
+\subsection{Error Handling Module}
+The error handling module provides mechanisms for capturing and handling errors at runtime.
+
+\subsection{Execution Environment Module}
+The execution environment module defines the execution environment of the Psi language.
+
+\subsection{Interpreter Module}
+The interpreter module executes operations based on the AST within the execution environment.
+
+\subsection{Mathematics Foundation Module}
+The mathematics foundation module provides basic mathematical functions and constants.
+
+\subsection{Documentation Module}
+The documentation module provides API interface descriptions and usage examples.
+
+\section{Getting Started}
+This section explains how to get started with the Psi CLI language.
+
+\section{Keywords}
+This section lists the keywords used in the Psi CLI language.
+
+\section{Contribution}
+This section outlines how to contribute to the Psi project.
+
+\section{License}
+This section provides information about the license of the Psi CLI language.
+
+\section*{Acknowledgment}
+The authors would like to thank...
