 - Run the `grunt` command to build/test (or alternatively, open the `tests/index.html` file to run the tests).
 - When committing, please omit checking in the files in the `dist/` folder after building/testing. These are only committed to the repository for users downloading Autolinker via Bower. I will build these files and assign them a version number when merging your PR.
