In recent months we have been seeing *tremendous* growth and interest in the [Ubuntu SDK](https://developer.ubuntu.com/get-started/) that is at the heart of building applications for Ubuntu for phones, tablets, desktops, and TVs. The SDK provides the ability to build rich native applications in QML/Qt that hook right into the system, platform services, messaging, social media and more. We will also be providing support for HTML5 apps soon (with deep platform integration), and for OpenGL apps too.

Today you can [download the SDK](https://developer.ubuntu.com/get-started/) and follow a [getting started tutorial](https://developer.ubuntu.com/resources/cookbook/mobile/currency-converter-phone-app/) to write your app. If you have Ubuntu running on a phone/tablet (find out how to install the daily images [here](https://wiki.ubuntu.com/Touch/Install)), you can test and run the application the device with just a click. The entire experience is all encased within our SDK IDE. We are still refining and improving many aspects of the SDK, and our Beta release will be in July.

When most developers are learning a new platform or technology, you have lots of questions. How do I do X? How do I do Y? While we can get our new developers up and running quickly with the SDK and tutorial, we also want to help provide as many answers to these common questions too. This is where the new cookbook comes in.

## The App Developer Cookbook

Today we are introducing the [Ubuntu App Developers Cookbook on developer.ubuntu.com](https://developer.ubuntu.com/cookbook/). The cookbook provides a number of different pages (e.g Device Sensors, Files and Storage, Games, General App Development, Multimedia, Networking etc) with a list of common questions and their associated answers.

Instead of building an entirely new piece of infrastructure, we wanted to work with the place where our developers naturally ask their questions; [AskUbuntu](https://askubuntu.com/), the Ubuntu themed StackExchange site we use for all our Q+A needs across the Ubuntu community.

Here’s how it works: when you have a question, simply [browse the cookbook](https://developer.ubuntu.com/cookbook/) to find an answer for your query. If you don’t, simply [ask that question on AskUbuntu](https://www.askubuntu.com/questions/ask?tags=application-development), and when a question has received two up-votes and an accepted answer, it will be added to the cookbook. This will ensure the very best content appears on the cookbook for current and new Ubuntu developers to enjoy.

What you see today is a first iteration of the cookbook. In the next few weeks we will be making some additional improvements:

* Refining the questions listed in the cookbook.
* Enhancing the navigation of the cookbook pages.
* Adding sub-sections to make content easier to navigate.
* Having a different cookbooks for Native (QML/Qt apps), HTML5, OpenGL, and Scopes.

If you have any questions or queries about the cookbook, feel free to share in the comments!

## How To Help

One of the core foundational strengths of Ubuntu is our community, and we are looking for help in ensuring our cookbook is as capable and comprehensive as possible. As such, we would like to encourage our community to do the following:

* Be sure to [ask questions on AskUbuntu](https://www.askubuntu.com/questions/ask?tags=application-development) for topics not covered by the cookbook.
* When you ask a question, be sure to accept the answer when it answers the question otherwise it won’t be accepted into the cookbook.
* Be sure to upvote questions that you find useful.

Thanks for continuing to help make the Ubuntu App Dev community a fun, dynamic, and innovative place to be!
