+CGI interface support for [Antd server](https://github.com/lxsang/ant-http)
+
+## Build from source
+As **cgi** is an **Antd's** plugin, it need to be built along with the server. This require the following application/libraries to be pre installed:
+
+### build dep
+* git
+* make
+* build-essential
+
+### server dependencies
+* libssl-dev
+* libsqlite3-dev
+
+### build
+When all dependencies are installed, the build can be done with a few single command lines:
+
+```bash
+mkdir antd
+cd antd
+wget -O- https://get.makeand.run/antd | bash -s "cgi"
+```
+The script will ask you where you want to put the binaries (should be an absolute path, otherwise the build will fail) and the default HTTP port for the server config.
+
+## Example of using PHP-CGI with Antd
+Make sure **php-cgi** is installed on your system.
+Enable **CGI** for PHP file using antd's config file in ```/path/to/your/build/config.ini```
+```ini
+; Example of antd's config file
+[SERVER]
+port=9192 ; port
+plugins=/path/to/your/build/plugins/ ; plugins dir
+plugins_ext=.dylib ; plugins extensions
+database=/path/to/your/build/database/
+htdocs=/path/to/your/build/htdocs
+tmpdir=/path/to/your/build/tmp/
+workers=4
+backlog=5000
+ssl.enable=1
+ssl.cert=/path/to/your/build/server.crt
+ssl.key=/path/to/your/build/server.key
+
+[FILEHANDLER]
+; using cgi interface for PHP file
+php=cgi
+```
+Next you need to tell the **cgi** plugin where to find the **php-cgi** command by create a ```cgi.ini``` in ```/path/to/your/build/plugins/cgi/cgi.ini```
+```ini
+;example of cgi.ini
+[CGI]
+;specify the path to php-cgi for php file
+php=/usr/bin/php-cgi
+```
+
+To run the Antd server with the **cgi** plugin:
+```sh
+/path/to/your/build/antd
+```
+
+**php** Web applications can be put on **/path/to/your/build/htdocs**
