 ## Development
 
-We encourage you to use docker for common operations like running tests, or debugging your code. Running `make sh` will start a new container instance based on the `Dockerfile` provided at root, finally a shell prompt will be displayed on your terminal. Also, syncronization with your local files will be already set.
+### Setup
 
-### Tests
-`make test` will trigger the excution of both running tests and running rubocop as linter, by simply running `rake`, this actions will be run inside a new container but using your local files.
+Run `bundle install` to install dependencies needed for local development.
 
-### Format
+### Tests
 
-`make format` will run `rubocop -a` which stands for _autocorrect_ and format your code according to the `.rubocop.yml` config file.
+`bundle exec rspec` will trigger the excution of running tests.
