 #### Adding taxonomic labels
 
-If input spacers or genomes are supplied together with taxonomic identifiers, lowest common ancestors are computed for each spacer or each phage and the [SpacePHARER output](#the-spacepharer-output) will contain taxonomic information for each match.
+If input spacers are supplied together with taxonomic identifiers, lowest common ancestors (LCA) of the phages are computed for each spacer. If input genomes are supplied together with taxonomic identifiers, the LCA of the host are computed for each phage.
