+  BREAKING: You must now `require 'slackistrano/capistrano'` in your Capfile.
+  Previously it was just `require 'slackistrano'`. It is also no longer necessary
+  to add `require: false` in your Gemfile, but it won't hurt to leave it.

+  Your files should now look like this:
+
+  Gemfile:

+    gem 'slackistrano'
+
+  Capfile:
+
+    require 'slackistrano/capistrano'
