-## Overall
-
-### Process
-
-1. The Parsing Module reads `llcppg.cfg` to obtain dynamic libraries, header files, and the package name. After parsing, it writes the generated `llcppg.symb.json` path into `llcppg.cfg`.
-2. The Function Declaration Generation Module reads `llcppg.cfg` to get the package name, header files, and the previously generated `llcppg.symb.json`. After parsing, it generates the function prototype `llcppg.function.json`.
-3. Reads the previously generated `llcppg.information.json`, stores it as a structure, and uses gogen to generate code based on the structure.
-
-## Parsing Module
-
-### Input
-
-Obtains the paths to header files and dynamic library files by reading the JSON file `llcppg.cfg`.
-
-```json
-{
-  "name": "inih",
-  "cflags": "$(pkg-config --cflags INIReader)",
-  "include": [
-    "INIReader.h",
-    "AnotherHeaderFile.h"
-  ],
-  "libs": "$(pkg-config --libs INIReader)",
-  "trimPrefixes": ["Ini", "INI"]
-}
-```
-
-```bash
-llcppsymg config-file
-```
-
-### Implementation Steps
-
-1. Parse dylib and store:
-
-```go
-// types.go
-type CPPSymbol struct {
-    Symbol string `json:"symbol"`
-    Type   string `json:"type"`
-    Name   string `json:"name"`
-}
-
-// parser_dylib.go
-func parseDylibSymbols(lib string) ([]common.CPPSymbol, error) 
-```
-
-2. Parse header files and store:
-
-```go
-// common.go
-type ASTInformation struct {
-    Namespace   string      `json:"namespace"`
-    Class       string      `json:"class"`
-    Name        string      `json:"name"`
-    BaseClasses []string    `json:"baseClasses"`
-    ReturnType  string      `json:"returnType"`
-    Location    string      `json:"location"`
-    Parameters  []Parameter `json:"parameters"`
-    Symbol      string      `json:"symbol"`
-}
-
-type Parameter struct {
-    Name string `json:"name"`
-    Type string `json:"type"`
-}
-
-// parser_ast.go
-func parseHeaderFile(config types.Config) ([]common.ASTInformation, error)
-```
-
-3. Cross-reference data from the first two steps to get the final output
-
-```go
-// common.go
-type SymbolInfo struct {
-    Mangle string `json:"mangle"` // C++ Symbol
-    CPP    string `json:"c++"`    // C++ function name
-    Go     string `json:"go"`     // Go function name
-}
-
-// common_symbols.go
-func getCommonSymbols(dylibSymbols []common.CPPSymbol, astInfoList []common.ASTInformation) []common.SymbolInfo {
-```
-
-4. Generate `llcppg.symb.json` file and store the JSON file path into `llcppg.cfg`
-
-```go
-func generateJSON([]CommonSymbolInfo)
-```
-
-5. Example `llcppg.symb.json` file
-
-```json
-{
-    "FunctionName": "A::B::C",
-    "Symbol": "_ZN9INIReaderC1ERKNSt3__112basic_stringIcNS0_11char_traitsIcEENS0_9allocatorIcEEEE",

-```
-
-## Function Declaration Generation Module

-### Input
-
-No input required, directly reads the `llcppg.cfg` file
-
-### Implementation Steps
-
-1. Execute the executable

-```
-
-2. Parse header files
-

-    Name string `json:"name"`
-    Type string `json:"type"`
-}
-
-// parser_ast.go
-func ParseHeaderFile(filePath string) ([]common.ASTInformation, error)
-```
-
-3. Generate the final JSON mapping file `llcppg.information.json`
-
-```go
- func GenerateJSONFile(info []common.ASTInformation)
-```
-
-```json
-{
-    "functionName": "A::B::C",

-## Code Generation Module
-
-### Input
-
-No input required, directly reads `llcppg.information.json` file
-
-### Implementation Steps
-
-1. Execute the executable
-
-```bash

-```
-
-2. Parse JSON file
-
-```go
-// common.go
-type HeaderFileInfo struct {
-    FunctionName     string            `json:"functionName"`

-    Parameters       map[string]string `json:"parameters"`
-}
-
-// parse_json.go
-func ParseJSON(jsonFilePath string) ([]common.HeaderFileInfo, error)
-```
-
-3. Generate code using the parsed structure with gogen
-
-```go
-// generator.go
-func GenerateCode(info []common.HeaderFileInfo) {
-    pkg := gogen.NewPackage("", PackageName, nil)
-    cm := comment(fmt.Sprintf("llgo:link %s %s", funcName1, symbol1))
-    pkg.NewFunc(recv, funcName, params, results, variadic).SetComments(pkg, cm).BodyStart(pkg).End()
-}
-```
-
-### Output
-
-1. Directory structure
-
-```bash
-package_name/
-├── _demo
-    ├── demo1.go
-└── llgo_link.go
-└── a.go
-└── b.go
-└── c.go
-```
-
-Note that `demo1.go` file needs to be written by the user
-
-2. `llgo_link.go` is responsible for linking configuration
-
-```go
-package inih
-const (
-        LLGoFiles   = "$(pkg-config --cflags INIReader): _wrap/reader.cpp"
-        LLGoPackage = "link: $(pkg-config --libs inih INIReader); -linih -lINIReader"
-)
-```
-
-3. Example content for `a.go`
-
-```go
-package inih
-import (
-        _ "unsafe"
-        "github.com/goplus/llgo/c"
