-## Usage
-
-```sh
-llcppg [config-file]
-```
-
-If `config-file` is not specified, a `llcppg.cfg` file is used in current directory. The configuration file format is as follows:
-
-```json
-{
-  "name": "inireader",
-  "cflags": "$(pkg-config --cflags inireader)",
-  "include": [
-    "INIReader.h",
-    "AnotherHeaderFile.h"
-  ],
-  "libs": "$(pkg-config --libs inireader)",
-  "trimPrefixes": ["Ini", "INI"]
-}
-```
-
-## Design

-llcppg Design
-=====
-
-## Usage
-
-```sh
-llcppg [config-file]
-```
-
-If `config-file` is not specified, a `llcppg.cfg` file is used in current directory. The configuration file format is as follows:
-
-```json
-{
-  "name": "inih",
-  "cflags": "$(pkg-config --cflags inireader)",
-  "include": [
-    "INIReader.h",
-    "AnotherHeaderFile.h"
-  ],
-  "libs": "$(pkg-config --libs inireader)",
-  "trimPrefixes": ["Ini", "INI"],
-  "cplusplus":true
-}
-```
-
-## Steps
-
-1. llcppsymg: Generate symbol table for a C/C++ library
-2. Manually modify the desired Go symbols in symbol table
-3. llcppsigfetch: Fetch information of C/C++ symbols
-4. gogensig: Generate a go package by information of symbols
-
-
-### llcppsymg
-
-```sh
-llcppsymg config-file
-llcppsymg -  # read config from stdin
-```
-
-It generates a symbol table file named `llcppg.symb.json`. Its file format is as follows:
-
-```json
-[
-  {
-    "mangle": "_ZN9INIReaderC1EPKcm",
-    "c++": "INIReader::INIReader(char const*, unsigned long)",
-    "go": "(*Reader).Init__0"
-  }
-]
-```
-
-
-### llcppsigfetch
-
-```sh
-llcppsigfetch config-file
-llcppsigfetch -  # read config from stdin
-```
-
-It fetches information of C/C++ symbols and print to stdout. Its format is as follows:
-
-```json
-[
-  {
-    "path": "/path/to/file.h",
-    "doc": {
-      "decls": [],
-      "macros": [],
-      "includes": [
-        {
-          "path": "incfile.h"
-        }
-      ]
-    }
-  }
-]
-```
-
-### gogensig
-
-```sh
-gogensig ast-file
-gogensig -  # read AST from stdin
-```
