-# 1st-gen/package.json
-# 1st-gen/projects/css-custom-vars-viewer/package.json
-# 1st-gen/projects/example-project-rollup/package.json

 ```bash
-cd 1st-gen && yarn tsc --version
+yarn tsc --version  # Check hoisted version
+cd 1st-gen && yarn tsc --version  # Verify in 1st-gen
+cd 2nd-gen && yarn tsc --version  # Verify in 2nd-gen
