+# node-cgi
+
+This library is a CGI adaptor for node.js
+
+It is designed to help people run node.js websites off of a shared server (CGI is so old it's available almost *everywhere*).
+
+## Usage
+
+You'll have to create a `.htaccess` file that rewrites everything to a CGI script:
+
+    Options +ExecCGI
+    AddHandler cgi-script cgi
+
+    RewriteEngine on
+    RewriteCond %{REQUEST_FILENAME} !-f
+    RewriteRule (.*) server.cgi
+
+Copy `cgi.js` to the same directory and make the actual CGI script (`server.cgi` in this example):
+
+    #!/usr/bin/env node
+
+    var cgi = require('./cgi');
+
+    var server = cgi.createServer(function(request, response) {
+        response.writeHead(200, {'Content-Type': 'text/plain'});
+        response.write('This is CGI!');
+        response.end();
+    });
+    server.listen();
+
+As you can see, using the `cgi` library is very similar to the `http` library in node.js
