+- ***My Ruby version is very old, can I use this?***
+
+When your Ruby is old, and you don't want to upgrade, and you want to
+control which libraries you use, you can use Bundler.
+
+In a Gemfile, perhaps in a non-deployed `:development` group, add this
+gem:
+
+```ruby
+group :development do
+  gem 'github_changelog_generator', require: false
+end
+```
+
+Then you can keep back dependencies like rack, which currently is only
+compatible with Ruby >= 2.2.2. So, use an older version for your app by
+adding a line like this to the Gemfile:
+
+```
+gem 'rack', '~> 1.6'
+```
+
+This way, you can keep on using github_changelog_generator, even if you
+can't get the latest version of Ruby installed.
