The good news is if students discover errors or optimizations, the code will be updated. The unfortunate side effect is that this will destroy Github forks and stars as well as require the code to be re-downloaded to get the newest updates. So my humble suggestion is to **NOT** fork or star this repository. Instead, you can bookmark this page. If you are not checking out branches and instead making the app the **thorough way** you can check out the change log to see what was fixed. If you're working through the **fast way** you can re-clone the repository.\n\n##Changelogs\n\n- **1/26/2016** : [Changelog](https://docs.google.com/document/d/1SgBmUu7COQQT5maqKVvIV4Iv0Oyva9-9-YRnpQ88XuY/pub)\n- **12/10/2015** : [Changelog](https://docs.google.com/document/d/1A5BSoLyEHkXrcBC50lNXqrl1Rkh0G2nM-h4ER8lKovw/pub)\n- **11/30/2015** : Lesson 1 and 2 launch\n # Archival Note \n This repository is deprecated; therefore, we are going to archive it.
