No problem! There are a variety of resources available to get you up and running, and sprinting once you're up and running.

• GitHub repository - This very page!
• Download - Download a compiled application for Linux, Mac OS X, or Windows.
• Website - Full documentation including tutorials, reference, pins maps, FAQ and much more!
• Wiki - Find basic information and tutorials here.
• LaunchPad forum at 43oh - A community around the original LaunchPad but also the newer ones.
• StellarPad forum at Stellaristi - A community more focused on the newer Stellaris LaunchPad.
• Bug report - Is something not working as it ought to? Or better yet, is there something we could make better?

Energia consists of the main repository and a submodule called emt. The emt tree contains the sources for the Energia MT (Multi Tasking) feature that is based on TI-RTOS/SYSBIOS. To clone Energia and the emt submodule:

git clone --recursive https://github.com/energia/Energia.git

If you already have a clone of Energia then:

git submodule update --init --recursive
git submodule sync
cd emt
git pull
cd ..
