# Ruby Versions

## How do I specify my app's Ruby version?

You have two options:

* Write your Ruby version to a file called `.ruby-version` in the root of your git repo
  * `echo "2.6.3 > .ruby-version"`
  * `git add .ruby-version`
  * `git commit -m "Set ruby version"`
* Or you can manage it in your Gemfile
  * `ruby "2.6.3"`
  * `bundle`
  * `git add Gemfile Gemfile.lock`
  * `git commit -m "Set ruby version"`

For legacy versions of Ruby, we only support the latest patch versions.
