     Barcodes, which can also be referred to as adaptors, tags, indices, molecular identifiers (MIDs), come in various library designs. 
-    At present, NextITS supports two barcoding schemes: dual-barcoding (which is the default) and single-barcoding. 
-    For the dual-barcoding scheme, the amplicon should have *the same barcode* on both ends. 
-    An asymmetric design, where each side of the amplicon has a *different barcode pair*, is still in development.  
+    At present, NextITS supports 4 barcoding schemes: dual-barcoding (symmetric, assymetric, or mixture of combinatorial tags) and single-barcoding. 
+    For the dual-barcoding scheme, the amplicon should have the barcode on both ends of the amplicon. 
+    An asymmetric design, where each side of the amplicon has a *different barcode pair*, is also supported.
