+What it does
+============
+
+Export sequences from an ampvis2 object and optionally add taxonomy to the fasta header lines.
+
+The Galaxy tool calls the `amp_export_fasta
+<https://madsalbertsen.github.io/ampvis2/reference/amp_export_fasta.html>`_ function
+of the ampvis2 package.
+
+Input
+=====
+
+@HELP_RDS_INPUT@
+
+In order to work the ampvis2 rds data set needs to contain sequence information.
+
+Output
+======
+
+The sequences contained in the input as fasta.
