+We maintain four views of WNV evolution:
+
+The first is [`wnv/global`](https://next.nextstrain.org/staging/WNV/global), which focuses on broader viral diversity for all WNV sequences submitted to GenBank which contain at least 75% of the genome length.
+
+The second is [`wnv/wa`](https://next.nextstrain.org/staging/WNV/global), which focuses on Washington State WNV virus sequences with tiered subsampling from Washington, the surrounding states, and across the USA.
+
+The third is [`wnv/lineage-1A`](https://next.nextstrain.org/staging/WNV/lineage-1A), which focuses on lineage 1A and uses X as the reference.
+
+The third is [`wnv/lineage-2`](https://next.nextstrain.org/staging/WNV/lineage-2), which focuses on lineage 2 and uses X as the reference.
+
+#### Underlying data
+
 We curate sequence data and metadata from NCBI as starting point for our analyses. For global lineage designations, we query [pathoplexus](https://pathoplexus.org/) for lineage assignments and exclusively work with NCBI-sourced records at this time. Curated sequences and metadata are available as flat files at:
