Bookmarking websites might be the one thing most of us have been doing the longest on computers. In general, bookmarking has stayed the same for decades, but there's a lot of great new bookmarking tools that we looked at in our Guide to Bookmarking. We looked several browsers and apps that let you bookmark pages, but perhaps the most intriguing of them all is Unmark, a free app from the good folks at Plain that encourages you to categorize your bookmarks by what you want to do with them—read the enclosed article, buy the listed product, watch the accompanying YouTube video or listen to the featured track.

The best part about Unmark is that it's also available as an open-source version that you can host and run on your own server for free. Going self-hosted means all your data stays with you, and you don't have to worry about the service getting an update you don't like, or the service being shut down. And since the open-source version is hosted on GitHub, users with development skills can change the way it looks and works, and share these modifications with other Unmark users.

Today we're going to take you the process of setting up Unmark on your own server. All you need is a domain name and web hosting account with access to a MySQL database. Once you've got Unmark installed, you'll be able to use your very own bookmarking service from anywhere (including mobile browsers), on your domain, without restrictions. Bookmarking with Unmark is as simple as clicking a bookmarklet or using the extension for Chrome. Sound like fun? Let's do this!
