+If you want to ignore a `package.json` (for example to find the parent `package.json` of the parent module), you can pass an
+ignore parameter (default: 0) saying how many `package.json`s you want to ignore when searching:
+
+```javascript
+var pathToParentOfParent = parent(null, 1).path; // Or, even more complicated:
+var pathToParentOfParentOfCustomPath = parent('/My/Cool/Folder', 1).path;
