+**What it does**
+
+This tool downloads a specified database from @snpeff_database_url@. It deposits it into the history.

+-------
+
+.. class:: infomark
+
+**The usage scenario**
+
+Suppose you want to annoate a VCF file containing variants within mm10 version of the Mouse genome. To do this you can:
+
+    #. Download mm10 snpEff database by typing *mm10* into **Select the annotation database...** text box.
+    #. Use **SnpEff eff** by choosing the downloaded database from the history using *Downloaded snpEff database in your history* option of the **Genome source** parameter.
