Developer Intro: An intro to all our various APIs and ways to customise with or integrate into Songbird. Read this if you're new to Songbird development.
Articles: Human-readable development articles categorised by concepts (e.g. Web Mashups, Appearances, Playlists, XPCOM, etc.) Read the Getting Started guides to quickly get off the ground running.
Examples: 100% complete from start to finish sample code for each of our APIs. Here lies a complete extension, sparkling Feathers, and 100% working music store/music blog code utilising our Webpage API.
Recipe Book: 100% free, MIT-licensed, highly reusable code snippets to quickly do things like "Make a bookmark", "Stop playback", or "Add a webpage listener". Copy and paste and re-use to your heart's content!
Reference Docs: All the hairy nitty-gritty technical docs, design docs, and API references. These are pretty deep-dive docs, and aren't necessarily as "friendly" as the human-readable articles.

If you're doing core Songbird player development, come by our sb_core Google Group for support.

Welcome to the Songbird Developer Wiki. This is a technical users' repository. If you're just looking to install and use Songbird to listen to music, you probably want to head back to the 'nest!

Within the wiki you can find information about the project, how to hack on it, how to get code submitted to the project, how to create your own add-ons, developer support and resources, and a whole slew of other information to hopefully help in your Songbird development.

New to Songbird Development?

If you don't know the difference between an Extension and a Feather - no worries! Songbird has a ton of APIs available and different ways of integrating into it... knowing exactly what to build or how to integrate into Songbird can be overwhelming.

We've put together a Developer Intro page to help you figure out what you can build and how you can build it.

APIs, and the people who (ab)use them...

Web Developers	Web developers building online music stores & media Web services should refer to our Webpage API resources.

Visual Designers	Firefox themers, Winamp skinners, visual designers, and artists, please refer to our Feathering resources.

Extension Gurus	Firefox extension and Winamp plug-in developers, you know what to do... see our Extensions resources.

JS/C/C++ Developers	Application developers can hack on and improve the core Songbird player. Check out our Core Development resources, and join the sb_core developer group. Or just jump straight to SVN info!
