+# Servactory style for RuboCop
+
+## Installation
+
+First add this to your Gemfile:
+
+```ruby
+gem "servactory-rubocop", require: false, group: %i[development]
+```
+
+Then run `bundle`, then `bundle binstubs rubocop`.
+
+Then add a default `.rubocop.yml` file in the root of your application with:
+
+```yml
+inherit_gem:
+  servactory-rubocop: rubocop-rails.yml
+  # or
+  # servactory-rubocop: rubocop-gem.yml
+```
+
+Now you can run `./bin/rubocop` to check for compliance and `./bin/rubocop -a` to automatically fix violations.
