RVM, the ruby version manager, is a fairly flexible tool that supports a number of workflows. The rvm utility can be used to generate both a .ruby-version file and a .ruby-gemset file for a given project.

```
$ rvm --ruby-version use 2.5.3@my_project
```

This will generate a .ruby-version file in your current project directory that points RVM to the 2.5.3 version of Ruby. It will also create a .ruby-gemset file that RVM will use for managing this project’s gemset.

# create and use the new RVM gemset
$ rvm use --create ruby-2.5.0@awesome_rails_project

# install rails into the blank gemset
$ gem install rails

# generate the new rails project
$ rails new awesome_rails_project

# go into the new project directory and create an .rvmrc for the gemset
