+description: |
+  pyUCell is a package for evaluating gene signatures in single-cell datasets.
+  pyUCell signature scores, based on the Mann-Whitney U statistic, are robust
+  to dataset size and heterogeneity, and their calculation demands less
+  computing time and memory than other available methods, enabling the
+  processing of large datasets in a few minutes even on machines with limited
+  computing power.
