+# See https://help.github.com/articles/ignoring-files for more about ignoring files.
+#
+# If you find yourself ignoring temporary files generated by your text editor
+# or operating system, you probably want to add a global ignore instead:
+#   git config --global core.excludesfile '~/.gitignore_global'
+
+# Ignore bundler config.
+/.bundle
+
+# Ignore the default SQLite database.
+/db/*.sqlite3
+/db/*.sqlite3-journal

+# Ignore all logfiles and tempfiles.

+* Database creation
+
+* Database initialization
+
+* How to run the test suite
+
+* Services (job queues, cache servers, search engines, etc.)
+
+* Deployment instructions

+#   cities = City.create([{ name: 'Chicago' }, { name: 'Copenhagen' }])
+#   Mayor.create(name: 'Emanuel', city: cities.first)
