+
+## 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
+
+See [llcppg Design](design.md).

+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
+```
