It contains a file, config, which is a YAML file that saves the options you ran bundler with, that way they can become the default. Sometimes, if you run certain commands, it can contain a cache of your gems. But that's not usual. Also, you'll want to put .bundle in your .gitignore, and Gemfile and Gemfile.lock into your repository UNLESS you're developing a gem, in which case, you just want the Gemfile.
