+  description: |
+    The Xerus library is a general purpose library for numerical calculations with higher order tensors, Tensor-Train Decompositions / Matrix Product States and other Tensor Networks.
+    The focus of development was the simple usability and adaptibility to any setting that requires higher order tensors or decompositions thereof.
