 **What it does**
 
-The key parameter for this mode is the overlaps size cutoff (option –m). By default it is set to half of the reads length, which is quite conservative. If your sequencing project is well covered (>50-100x) you may try increasing a bit this value. The minCoverage is an important parameter which is automatically determined. You may check this value in the program output and possibly override it.
+Edena is an overlaps graph based short reads assembler and is suited to Illumina GA reads. An assembly with Edena is a two step process: overlapping and assembling.
+
+In the assembling step, the overlapping file (produced in the previous step) is provided to the program, as well as some assembly parameters. A set of contigs in FASTA format is outputted. The purpose of having a two step process is that the overlapping file is computed only once and can then be used to produce assemblies with different parameters.
