Making homebrew

Homebrew application development for the Wii is both fun and challenging. If you want to develop homebrew for the Wii, you will need some tools.

Developing

You can use devkitPPC to develop applications. See https://devkitpro.org/wiki/Getting_Started for setup instructions.
The list of development tools contains many code libraries and resources that are useful for developing.
There are various tutorials available.

If you would like to create a page for your application while developing it, create it in your user namespace and link to it on the List of homebrew in development page. You can move it to the article namespace when it is released.
It is strongly recommended to create icon.png and meta.xml files for your application to make it fully compatible with the Homebrew Channel.
When your application is ready to be released, you can create a page for your application in the article namespace. Make sure to add the {{infobox homebrew}} template and fill it in as much as you can. AByrne55 also offers services to help you create an application page.
If you would like, you can host your application here on wiibrew by uploading it. Otherwise, you can upload it somewhere else and link to it. People who are offering Wii Homebrew Hosting: PineCone, Vithon, Calthephenom, and Daltonlaffs. You can also post your app for download on GitHub. GitHub also allows people to notify you of issues with your application and to suggest changes.
Please, for the love of Team Twiizers, do NOT upload to RapidShare! They've been greedy for a while, but lately, it's difficult to find any time of day that the servers don't claim to be "overloaded", and thus unavailable for use by anyone without their overpriced "Premium" accounts. Use MediaFire or any other alternative upload service, just not RS!
