-### GO subset files
+## GO subset files
 GO subsets (also known as GO slims) are condensed versions of the GO containing a reduced number of terms. They are specified by tags within the ontology that indicate if a given term is a member of a particular subset. GO subsets are used to provide a broad overview of the range of functions and processes relevant to a gene or a goup of genes. More information and links for downloading subsets be found on the [Guide to GO subsets](/docs/go-subset-guide/) page.
