+in node.js or browsers. Requires [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/API/ArrayBuffer)
+and [DataView](https://developer.mozilla.org/en-US/docs/Web/API/DataView)
+support.
 
 ## usage

+## example
+
+in node:
+
 ```js
-var dbf = require('dbf');
+var dbf = require('../'),
+    fs = require('fs');
 
-dbf.writer([{
-    type: 'C',
-    name: 'foo'
-}], [{
-    foo: 'bar'
-}]);
+var buf = dbf.structure([
+    {foo:'bar',noo:10},
+    {foo:'louie'}
+]);
+
+fs.writeFileSync('foo.dbf', toBuffer(buf.buffer));
+
+function toBuffer(ab) {
+    var buffer = new Buffer(ab.byteLength);
+    var view = new Uint8Array(ab);
+    for (var i = 0; i < buffer.length; ++i) {
+        buffer[i] = view[i];
+    }
