+# example
+
+you can copy objects shallowly:
+
+``` js
+var copy = require('shallow-copy');
+
+var obj = { a: 3, b: 4, c: [5,6] };
+var dup = copy(obj);
+dup.b *= 111;
+dup.c.push(7);
+
+console.log('original: ', obj);
+console.log('copy: ', dup);
+```
+
+and you can copy arrays shallowly:
+
+``` js
+var copy = require('shallow-copy');
+
+var xs = [ 3, 4, 5, { f: 6, g: 7 } ];
+var dup = copy(xs);
+dup.unshift(1, 2);
+dup[5].g += 100;
+
+console.log('original: ', xs);
+console.log('copy: ', dup);
+```
+
+# methods
+
+``` js
+var copy = require('shallow-copy')
+```
+
+## copy(obj)
+
+Return a copy of the enumerable properties of the object `obj` without making
+copies of nested objects inside of `obj`.
+
+If `obj` is an array, the result will be an array.
+If `obj` is an object, the result will be an object.
+If `obj` is not an object, its value is returned.
