+```
+gem 'solidus_nexio', path: '~/apps/solidus_gems/solidus_nexio'
+```
 
-To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
+2. Uncomment the line #45 in `app/helpers/solidus_nexio/checkout_helper.rb`
