+## Nextstrain clades
+
+Since its emergence in late 2019, SARS-CoV-2 has evolved into many co-circulating variants. To facilitate discussion of these variants, we have grouped them into clades which are defined by specific signature mutations.
+
+Nextstrain clade names consist of two numbers representing a year and then a single letter representing the clade within that year. For example, 21A is the first clade we named in 2021.
+
+We define each clade by a combination of signature mutations. You can find the exact clade definition on Github in this [file](https://github.com/nextstrain/ncov/blob/master/defaults/clades.tsv).
