+    longDescription = ''
+      paging-calculator is a CLI utility written in Rust that helps you find the indices that a virtual
+      address will have on different architectures or paging implementations.
+
+      It takes a (virtual) address in hexadecimal format and shows you which index will be used for
+      what page-table level. It can be installed with $ cargo install paging-calculator.
