+# Item Variants
+
+### What are Variants?
+
 A Item Variant is a version of a Item, such as differing sizes or differing colours (like a _blue_ t-shirt in size _small_ rather then just a t-shirt).
-Without Item variants, you would have to treat the _small, medium_ and _large_ versions of a t-shirt as three separate Items; 
+Without Item variants, you would have to treat the _small, medium_ and _large_ versions of a t-shirt as three separate Items;
 Item variants let you treat the _small, medium_ and _large_ versions of a t-shirt as variations of the one Item 't-shirt'.
 
+### Using Variants
+
+Variants can be based on two things
+
+1. Item Attributes
+1. Manufacturers
+
+### Variants Based on Item Attributes
+
 To use Item Variants in ERPNext, create an Item and check 'Has Variants'.
 
-* The Item shall then be referred to as a so called 'Template'. Such a Template is not identical to a regular 'Item' any longer. For example it (the Template) can not be used directly in any Transactions (Sales Order, Delivery Note, Purchase Invoice) itself. Only the Variants of an Item (_blue_ t-shirt in size _small)_ can be practically used in such. Therefore it would be ideal to decide whether an item 'Has Variants' or not directly when creating it.
