+**What it does**
+
+Reads are mapped to the genome using the Bowtie1 aligner. Reads mapping uniquely to the genome are assigned to subfamilies of repetitive elements based on their degree of overlap to RepeatMasker annotated genomic instances of each repetitive element subfamily. Reads mapping to multiple locations are separately mapped to repetitive element assemblies – referred to as repetitive element psuedogenomes – built from RepeatMasker annotated genomic instances of repetitive element subfamilies. RepEnrich then return tables of counts merged from both strategies, that can be further processed in statistical analysis for differential expression. For detailed information see the `original publication`_.

+**Outputs**
+
+(1) Fraction counts, (2) Family fraction counts and (3) Class fraction counts are returned in tabular format, for further statistical tests differential expression analysis or graphics 
+
+**RepEnrich**
+
+This Galaxy tool is a wrapper of the RepEnrich tool by steven_criscione@brown.edu et al. whose code and manual are available in `GitHub`_.
+
+.. _GitHub: https://github.com/nskvir/RepEnrich
+
+Python scripts RepEnrich.py and RepEnrich_setup.py have been adapted to python 3. Note that sorting of Fraction counts, Family fraction counts and Class fraction counts is  different with this Galaxy wrapper or with RepEnrich as found in the `RepEnrich code repository`_. However, this different sorting does not affect subsequent statistical analyses

+
+**Execution time**
+
+.. class:: warningmark
+
+This tool includes steps to index the reference genome, index repeat sequences and align reads to these indexes. Therefore the run time may be **long to very long**. 
+
+.. class:: infomark
+
+For more information on the tools, please visit our `code repository`_.
+
+If you would like to give us feedback or you run into any trouble, please send an email to artbio.ibps@gmail.com 
+
+This tool wrapper is developed by the `ARTbio team`_ at the `Institut de Biologie Paris Seine (IBPS)`_.
