+### Setup
+
+#### Install Ruby
+
+The currently required Ruby version is in the root folder inside the [.ruby-version](https://github.com/archivesspace/e2e-tests/blob/master/.ruby-version) file.
+
+It is strongly recommended to use a Ruby version manager to be able to switch to any version.
+The most popular version manager available for `Linux` and `macOS`, is `rbenv`.
+You can find the installation guide here [https://github.com/rbenv/rbenv#readme](https://github.com/rbenv/rbenv#readme).
+If you are on `Windows`, a separate `rbenv` installer exists here: [https://github.com/RubyMetric/rbenv-for-windows#readme](https://github.com/RubyMetric/rbenv-for-windows#readme).
+If you wish to use a different manager or installation method, you can choose one of the following: [https://www.ruby-lang.org/en/documentation/installation/](https://www.ruby-lang.org/en/documentation/installation/)
+
