+**eXpress Overview**
+
+eXpress is a streaming tool for quantifying the abundances of a set of target sequences from sampled subsequences. Example applications include transcript-level RNA-Seq quantification, allele-specific/haplotype expression analysis (from RNA-Seq), transcription factor binding quantification in ChIP-Seq, and analysis of metagenomic data.

+-----
+
+**Input format**
+
+eXpress requires two input files:
+
+- A multi-FASTA file containing the transcript sequences.
+- Read alignments to the multi-FASTA file in BAM format.
+
+------
+
+**Outputs**
+
+- The output for eXpress is saved in a file called results.xprs in an easy-to-parse tab-delimited format.
+
+- Also, params.xprs contains the values of the other parameters (besides abundances and counts) estimated by eXpress.
