-===========
+TN93
+----
+
+This is a simple program meant to compute pairwise distances between aligned 
+nucleotide sequences in sequential FASTA format using the 
+[Tamura Nei 93 distance](http://www.ncbi.nlm.nih.gov/pubmed/8336541).
+
+USAGE
+-----
+
+    usage: tn93 [-h] [-o OUTPUT] [-t THRESHOLD] [-a AMBIGS] [-l OVERLAP][-d COUNTS_IN_NAME] [-f FORMAT] [-s SECOND_FASTA] [-b] [-c] [-q] [FASTA]
+
+Try it from using the example file in 'data' by typing 
+
+    tn93 -t 0.05 -o data/test.dst data/test.fas
+
+Output (diagnostics written to stderr, histogram written to stdout so can be redirected)
+
+Example:
 
-Removes aligned sequences that are within a given distance from a reference
-sequence using the 1993 Tamura-Nei distance calculation.
+    Read 8 sequences of length 1320
+    Will perform 28 pairwise distance calculations
+    Progress:     100% (       7 links found,          inf evals/sec)
+    {

+NOTES
+-----
+
+All sequences must be aligned and have the same length.  Only IUPAC characters are recognized (e.g. no ~). Sequence names can include copy number as in 
+
+    >seqname:10
+
+':' can be replaced with another character using `-d`, and sequences that have no explicit copy number are assumed to be a single copy. Copy numbers 
+only affect histogram and mean calculations.
