+## Notes
+
+Rails 5 ships with a puma configuration that may conflict with Guard Jasmine if they're both running concurrently.
+
+To work around this, the `tmp_restart` plugin in config/puma.rb needs to be disabled for development mode.
+

+# Allow puma to be restarted by `rails restart` command.
+plugin :tmp_restart
+```
+
+To:
+
+```ruby
+# Allow puma to be restarted by `rails restart` command.
+plugin :tmp_restart unless ENV['RAILS_ENV'] == 'development'
