 ## Output example

@@ -226,31 +223,6 @@ 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 your 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.
