 ## Core documentation types
 
-The templates are categorised in line with standard [DITA](http://docs.oasis-open.org/dita/dita/v1.3/errata02/os/complete/part3-all-inclusive/archSpec/technicalContent/dita-technicalContent-InformationTypes.html#dita_technicalContent_InformationTypes) documentation types:
+The templates are categorised into three documentation types:
 
-**Concept**: Describes how and why things work. 
-Concepts are normally written to help the reader understand a technology, prior to using it.
+**Concept**:
+Describes how and why something works.
