+## Ruby SDK Testing
+
+This directory contains scripts for testing the Ruby SDK in various environments.
+
+### Test Ruby Gems Installation
+
+Verifies that the Ruby SDK can be installed from RubyGems in a variety of environments.
+
+The `test-rubygems-install.sh` script builds Docker images for Alpine and Debian and runs the test script inside each container.
+
+You should see output like the following if the tests pass:
+
+```
+Successfully installed eppo-server-sdk-3.3.0-aarch64-linux
+1 gem installed
+Installed version: 3.3.0
+✅ Installation successful in debian environment
+```
