 Just put something like this in your `Rakefile`:
 ```ruby

@ -216,6 +226,31 @@ If you're seeing this warning, please do the following:
 1. Make sure you're providing an OAuth token, so you're not making requests anonymously. Using an OAuth token increases your hourly request maximum from 60 to 5000.
 2. If you have a large repo with lots of issues/PRs, you can use `--max-issues NUM` to limit the number of issues that are pulled back. For example: `--max-issues 1000`
 - ***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.
