+**Note**
+
+This tool uses Weblogo3_ in Galaxy to generate a sequence logo. The input file must be a fasta file in your current history.
+
+It is recommended for (eg) viewing multiple sequence alignments output from the clustalw tool - set the output to fasta and feed
+it in to this tool.
+
+A typical output looks like this
+
+.. image:: ${static_path}/images/rgWebLogo3_test.jpg
+
+----
+
+**Warning about input Fasta format files**
+
+The Weblogo3 program used by this tool will fail if your fasta sequences are not all EXACTLY the same length. The tool will provide a warning
+and refuse to call the weblogo3 executable if irregular length sequences are detected.
+
+Fasta alignments from the companion ClustalW Galaxy tool will work but many other fasta files may cause this tool to fail - please do not file
+a Galaxy bug report - this is a feature of the tool and a problem with your source data - not a tool error - please make certain all your fasta
+sequences are the same length!
+
+----

+Weblogo attribution and associated documentation are available at Weblogo3_
