30+# We recommend against adding the Pods directory to your .gitignore. However
31+# you should judge for yourself, the pros and cons are mentioned at:

42+## Environment normalization:
43+/.bundle/

46+
47+# for a library or gem, you might want to ignore these files since the code is
48+# intended to run in multiple environments; otherwise, check them in:
49+# Gemfile.lock
50+# .ruby-version
51+# .ruby-gemset
