+An auto-generated changelog really helps, even if you manually fill in the release notes!

-- it's not so quite easy to find it in manually filled Releases notes.
-- this file can also help you to build your Release note and not miss features in manually-filled list.
+- it's not quite as easy to find this in handwritten releases notes
+- a generated file saves you the trouble of remembering everything;
+  sometimes people forget to add things to a handwritten file
 
-In the end:
+Ultimately, I think GitHub Releases is ideal for end-users. 
+Meanwhile, `CHANGELOG.md` lives right in the repository, with its detailed list of changes, which is handy for developers.
+Finally, there's nothing wrong with using GitHub Releases alongside `CHANGELOG.md` in this combination.
 
-I think, that GitHub Releases is more for end-users.
-But `CHANGELOG.md` could stay in the repo for developers with detailed list of changes.
-And it's nothing bad to combine GitHub Releases and `CHANGELOG.md` file together in that manner.

+GitHub [limits the number of API requests](https://developer.github.com/v3/#rate-limiting) you can make in an hour. You can make up to 5,000 requests per hour.

+- ***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.
