-- sequence alignment by [nextalign](https://docs.nextstrain.org/projects/nextclade/en/stable/user/nextalign-cli.html)
+- sequence alignment by [Nextclade](https://docs.nextstrain.org/projects/nextclade/en/stable/user/nextclade-cli/index.html)
 - masking several regions of the genome, including the first 1350 and last 6422 base pairs and multiple repetitive regions of variable length
 - phylogenetic reconstruction using [IQTREE-2](http://www.iqtree.org/)
 - ancestral state reconstruction and temporal inference using [TreeTime](https://github.com/neherlab/treetime)
