+- The **Mercury Libraries** are the collection of dependencies with the single cross version.
+We will represent as a single box here. But the real dependencies can of a subset of the Mercury Libraries.
+For more information about the Mercury Modules Interdependencies see [HERE](./mercury/mercury-library/README.md).
