11	+ == Description ==
12	+
13	+ Page Links To is a plugin that allows you to make a WordPress page or post link to a URL of your choosing, instead of its WordPress page or post URL. It also will redirect people who go to the old (or "normal") URL to the new one, using a redirect style of your choosing (`301 Moved Permanently` is standard, but you can enable `302 Moved Temporarily` redirects if you wish.)
14	+
15	+ This is useful for setting up navigational links to non-WordPress sections of your site or to off-site resources.
16	+
17	+ == Installation ==
18	+
19	+ 1. Upload the `page-links-to` folder to your `/wp-content/plugins/` directory
20	+
21	+ 2. Activate the "Page Links To" plugin in your WordPress administration interface
22	+
23	+ 3. Create (or edit) a page or a post to have a title of your choosing (leave the content blank)
24	+
25	+ 4. Down below, in the advanced section, find the Page Links To widget and add a URL of your choosing
26	+
27	+ 5. Optionally check the boxes to enable link opening in a new browser window, or `302 Moved Temporarily` redirects
28	+
29	+ 6. Save the post or page
30	+
31	+ 7. Done! Now that post or page will point to the URL that you chose
