Instructions - Jekyll version collision

[Cinntax]

Ran into an issue with the instructions on the readme. I think the install guide needs to start with only installing bundler, and then move into the project directory to install jekyll. Installing jekyll globally will install the latest version, colliding with that found in the gem.lockfile.

Does that sound right? I can submit a PR for the change but want to ensure we're aligned.

FWIW I also had various troubles getting this running. To isolate the environment (BTW not a Rubyist), I did the following with the checked out repo:

cd super-widget
bundle config path vendor/bundle
bundle install

Then I had to add vendor to the exclude list in _config.yml.

Then I could finally bundle exec jekyll serve

Also willing to submit a PR. Even better, though, recommend porting the whole thing to Hugo! ;-)
