You should use git add to specify the files you want for each commit, and you should not git commit -a because you'll get ./lib and ./docs included which we only want to include if we're doing a release.
When you run a build it'll also generate docs and lib, so be sure to not include them when committing. You can use git rm --cached ./dist ./lib to remove them from the staged changes.
Also, although bundles are currently created they aren't functional.
