+docuri
+======
+Rich document ids for CouchDB.
+
+`type/id/subtype/version/index`
+
+eg `movie/blade-runner/gallery-image/medium/12`
+
+## Usage
+Parse id string:
+```js
+require('docuri').parse('mytype/myid/mysubtype/myversion/myindex');
+// {
+//   type: 'mytype',
+//   id: 'myid',
+//   subtype: 'mysubtype',
+//   version: 'myversion',
+//   index: 'myindex'
+// }
+```
+
+Build id string from object:
+```js
+require('docuri').stringify({
+  type: 'mytype',
+  id: 'myid',
+  subtype: 'mysubtype',
+  version: 'myversion',
+  index: 'myindex'
+});
+// 'mytype/myid/mysubtype/myversion/myindex'
+```
+
+## Development
+To run the unit tests:
+```shell
+npm test
+```
+
+For JShint:
+```shell
+npm run jshint
+```
