+#. WoLr2 (“Web of Life” release 2): A significant upgrade from WoLr1. The genome
+   pool is an even representation of microbial diversity, sampled from
+   non-redundant bacterial and archaeal genomes from NCBI (RefSeq and GenBank,
+   complete and draft). A high-quality reference phylogeny was reconstructed
+   using the uDance workflow (manuscript in submission). Taxonomic
+   classifications were curated according to phylogeny based on GTDB (default)
+   and NCBI. Functional annotations were performed using EggNOG, GO, KEGG,
+   MetaCyc, Pfam and UniRef.

 #. WoLr1 ("Web of Life" release 1): An even representation of microbial diversity, selected using an prototype
    selection algorithm based on the MinHash distance matrix among all non-redundant bacterial and archaeal genomes
    from NCBI (RefSeq and GenBank, complete and draft), plus several genome quality control criteria. A
