# 󠀁[Twenty Fifteen](https://make.wordpress.org/core/2014/09/09/twenty-fifteen/)󠁿

It’s that time of the year again, time to work on a new default theme!
 This year
we’re back to creating a brand new design. Like Twenty Fourteen, this is being targeted
for December and thus WordPress 4.1.

[@matt](https://profiles.wordpress.org/matt/) asked Takashi Irie to design Twenty
Fifteen, and they are both closely collaborating with [@iandstewart](https://profiles.wordpress.org/iandstewart/),
who also worked on Twenty Ten and Twenty Eleven. The design is far from finished,
but the following screenshots might give you an idea of what direction it is headed
this year:

> Twenty Fifteen is a clean, blogblog (versus network, site)-focused theme designed
> through simplicity. With careful attention to typography, the theme treats text
> as a major part of the user interface. It features Google’s Noto Serif and Sans–
> a font family designed to be visually harmonious across many of the world’s languages,
> and a perfect fit for the internationalization strides being made in WordPress
> coreCore Core is the set of software required to run WordPress. The Core Development
> Team builds WordPress..
> The theme is also designed to maximize the impact of core’s customization tools–
> Custom Headers and Custom Backgrounds. These tools will allow any Twenty Fifteen
> blog to be easily personalized.
> Last but definitely not least, Twenty Fifteen uses a mobile first approach in 
> its design, remaining attractive and focusing on an optimal browsing experience
> across a wide array of devices from mobile to widescreen desktops.
> All of these things come together to present content cleanly for any of Twenty
> Fifteen’s users – a simple default theme.

Next steps will be to finish the design, create a working theme, commit that to 
core, and then break it and make sure it adheres to the high standards and expectations
we all have for default themes.

If you are interested in contributing, please subscribe to this blog (if you haven’t
already), and leave your name in the comments. As soon as it’s ready for public 
breaking, testing, and patching, I’ll make sure you get a pingPing The act of sending
a very small amount of data to an end point. Ping is used in computer science to
illicit a response from a target server to test it’s connection. Ping is also a 
term used by Slack users to @ someone or send them a direct message (DM). Users 
might say something along the lines of “Ping me when the meeting starts.”!
