-This work is made possible by the open sharing of genetic data by research groups from all over the world. We gratefully acknowledge their contributions.
+We gratefully acknowledge the authors, originating and submitting laboratories of the genetic sequences and metadata for sharing their work. This work is made possible by the open sharing of genetic data by research groups from all over the world. We gratefully acknowledge their contributions.
 
 Special thanks to Nick Loman, Nathan Grubaugh, Kristof Theys, Nuno Faria, Kristian Andersen, Andrew Rambaut and Karl Erlandson for data sharing, comments and suggestions.
+
+Please note that although data generators have generously shared data in an open fashion, that does not mean there should be free license to publish on this data. Data generators should be cited where possible and collaborations should be sought in some circumstances. Please try to avoid scooping someone else's work. Reach out if uncertain.
+
+We curate sequence data and metadata from NCBI as starting point for our analyses. Curated sequences and metadata are available as flat files at:
+
+* [data.nextstrain.org/files/workflows/zika/sequences.fasta.zst](https://data.nextstrain.org/files/workflows/zika/sequences.fasta.zst)
+* [data.nextstrain.org/files/workflows/zika/metadata.tsv.zst](https://data.nextstrain.org/files/workflows/zika/metadata.tsv.zst)
+
+Additionally, this Zika build incorporates data from https://github.com/blab/zika-usvi/.
