 ## Installation
 Add this lines to your application's Gemfile:
 
 ```ruby
 gem 'egov_utils'
-
-source 'https://rails-assets.org' do
-  gem 'rails-assets-tether', '>= 1.3.3'
-end
 ```
-Because it is not possible to add a tether as a dependency (as long as it is from other source), you need to add it to your own Gemfile.
 
 And then execute:
 ```bash
 $ bundle
 ```
