+===================================================================
+Filter genes based on number of cells or counts (`pp.filter_genes`)
+===================================================================
+
+Keep genes that have at least `min_counts` counts or are expressed in at
+least `min_cells` cells or have at most `max_counts` counts or are expressed
+in at most `max_cells` cells.
+
+Only provide one of the optional parameters `min_counts`, `min_cells`,
+`max_counts`, `max_cells` per call.
