 ## Development
 
-After checking out the repo, run `bin/setup` to install dependencies. You can
+Install rbenv and ruby-build to get a ruby 2.7.x on your system (running on ubuntu 20.04).
+
+    yay -S rbenv ruby-build
+
+Add the rbenv shell extension (`eval "$(rbenv init -)"`) to your shell config (e.g. `~/.zshrc`) and install ruby 2.7.0
+
+    rbenv install 2.7.0
+
+After checking out the repo verify, that your system is using the 2.7.0 ruby:
+
+    # rbenv version
+    2.7.0 (set by ..../sensu-plugins-minio/.ruby-version)
+
+Run `bin/setup` to install dependencies. You can
 also run `bin/console` for an interactive prompt that will allow you to
 experiment.
