+**What it does**
+
+This tool calculates a histogram of genome coverage depth based on mapped reads in BAM format or intervals in BED format.
+
+
+------
+
+.. class:: warningmark
+
+This tool requires that `bedtools`__ has been installed on your system.
+
+.. class:: infomark
+
+The output file will contain five columns:
+
+    * 1. Chromosome name (or 'genome' for whole-genome coverage)
+    * 2. Coverage depth
+    * 3. The number of bases on chromosome (or genome) with depth equal to column 2.
+    * 4. The size of chromosome (or entire genome) in base pairs
+    * 5. The fraction of bases on chromosome (or entire genome) with depth equal to column 2.
