 ## How does it work?
 It requires an important number of pre-computed datasets: 
-- A Core Genome and its Phylogenetic reconstructions for:
-    - The Phylogenetic clade of interest
-    - Two phylogenetic clades, outgroups of the clade of interest.
+- A Core Genome built with 3 clades and its Phylogenetic reconstruction:
+    - The clade of interest
+    - Two clades, outgroups of the clade of interest.
 
-*The core genomes for the three clades must be formated as HMMer database*
+Each core-gene alignment has to be divided by clade, so we can distinguish between the clade of interest and the outgroups. *The core genes for the three clades must be formated as HMMer database*
 
 - The Multiple sequence alignments of each Core-Gene
 - A list of reference sequences
