The Homebrew Launcher is a WiiU homebrew that lists homebrew applications located on a SD card and permits launching them (similar to the Homebrew Channel of the Wii).
To use the Homebrew Launcher (or HBL, for short) you must copy homebrew_launcher.elf into SD:/wiiu/apps/homebrew_launcher/homebrew_launcher.elf, and run the installer throught your WiiU browser.
The apps that will be listed are should be in the following path /wiiu/apps/homebrew_name/some_elf_name.elf on the root of the SD card. A meta.xml and an icon.png (256x96) are optional. Here is an example:
To build the main application devkitPPC is required as well as some additionally libraries. If not yet done export the path of devkitPPC and devkitPro to the evironment variables DEVKITPRO and DEVKITPPC.
For an example on how to build an application for the HBL check out the [Hello World example](https://github.com/dimok789/hello_world) application or the port of the libwiiu application [Pong](https://github.com/dimok789/pong_port) for HBL.
