2. You can add the rails gem with version greater than 1.1 (not including 1.1) and less than 3.0.

   bundle add rails --version "> 1.1, < 3.0"

3. You can use the https://gems.example.com custom source and assign the gem to a group.

   bundle add rails --version "~> 5.0.0" --source "https://gems.example.com" --group "development"

4. The following adds the gem entry to the Gemfile without installing the gem. You can install gems later via bundle install.
