 If you've used cognitive skills in the past, you already know that enriched content is created by *skillsets*. Skillsets move a document through a sequence of enrichments that invoke atomic transformations, such as recognizing entities or translating text. 
 
-Output can be a search index, or projections in a knowledge store. The two outputs, search index and knowledge store, are mutually exclusive products of the same pipeline. They are derived from the same inputs, but their content is structured, stored, and used in different applications.
+Output is always a search index, but it can also be projections in a knowledge store. The two outputs, search index and knowledge store, are mutually exclusive products of the same pipeline.

 + `tables` project enriched content into Table Storage. Define a table projection when you need tabular reporting structures for inputs to analytical tools or export as data frames to other data stores. You can specify multiple `tables` within the same projection group to get a subset or cross section of enriched documents. Within the same projection group, table relationships are preserved so that you can work with all of them.
