+## Scope of this dataset
+
+This dataset assigns genotypes to measles samples based on [criteria outlined by the WHO](https://www.who.int/publications/i/item/WER8709). 
+
+The WHO has defined 24 measles genotypes based on N gene and H gene sequences from 28 reference strains. For new measles samples, genotypes can be assigned based on genetic similarity to the reference strains at the "N450" region (a 450 bp region of the N gene). 
+
+The tree used in this dataset includes N450 sequences for the 28 reference strains, along with other representative strains for each genotype. 
+
+## Features
+
+This dataset supports:
+
+- Assignment of genotypes
+- Minimal sequence QC
+- Phylogenetic placement
+
+## What are Nextclade datasets
