+### Contributing guidelines
+
+In general, I follow the "fork-and-pull" Git workflow:
+
+1.  **Fork and clone** the repo on GitHub.
+2.  **Configure and install** the dependencies `npm install`.
+3.  **Create** a new branch: `git checkout -b branch-name`.
+4.  **Commit** all your changes to your branch. Please write a [good commit message](https://chris.beams.io/posts/git-commit/).
+5.  **Push** your work back up to your fork.
+6.  **Submit a Pull Request** so that I can review your changes. Please add documentation and some details to the PR.
+
+Keep your changes as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as separate pull requests. Work in Progress pull requests are also welcome to get feedback early on, or if there is something blocked you.

-Custom [RuboCop](https://github.com/rubocop/rubocop) extension template.
+This repository provides recommended [RuboCop](https://github.com/rubocop/rubocop) configuration and additional **accessibility RuboCop Rails cops** for use on open source and internal Rails projects.
+
+## Installation
+
+Install the `rubocop-rails-accessibility` gem
+
+```sh
+gem install rubocop-rails-accessibility
+```
+
+or if you use bundler put this in your `Gemfile`

-3. Run `bin/setup`
-4. Add your custom cop by running `bundle exec rake new_cop[Foo/Bar]`
-5. Edit `lib/rubocop/cop/foo/bar.rb`
+You need to tell RuboCop to load RuboCop Rails Accessibility.
+

+
+``` yaml
+inherit_gem:
