 ## Development
 
-After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+To update the gem version or dependencies within `bindings/ruby/Gemfile.lock`, run `bundle update --gemfile=bindings/ruby/Gemfile` from the project directory, or `cd bindings/ruby && bundle update`
 
-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 the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
