Hello I have created a new rails app, and added the lamby gem, however, running `./bin/rake -r lamby lamby:install` results into: ``` rake aborted! Don't know how to build task 'lamby:install' (See the list of available tasks with `rake --tasks`) ``` even if use `bundle exec`, I get the same issue, is there anything I am missing? or, do I have totally depend on lamby-cookiecutter template?
