+RUBY_VERSION=3.2.2

+# It is the easiest and simplest option, plus it comes with some handy plugins 
+# to let us easily manage environment variables in production.

+#
+#        gem install bundler -v 1.17.3
+#
+# but we install latest Bundler
+#
+gem install bundler
+
+
+# Test version of bundler
+#
+bundle -v
