-This is a guide to help you review an article of the wiki. Please check that all the following criteria are met to consider that a page is complete and correct.
-
-[ ] The article is correctly structured. 
-It should contain :
-1. Header with the following fields (please pay attention to block indentation)
----
-title: 
-tableColumns: 
-    article:
-        doi: 
-        abstract: 
-    Sensor: 
-    Activator: 
-    Effector: 
-    PFAM: 
----
-2. The following paragraphs
-- Description
-- Molecular mechanisms
-- Example of genomic structure
-- Distribution of the system among prokaryotes
-- Structure
-- Experimental validation
-- Relevant abstracts with the following structure
-::article-doi-list
----
-items:

-- References
-
-[ ] The header contains all the required information.
-The information provided in the header is required to display the list of defense systems. The mandatory fields are : ```title:```, ```article```, ```doi```, ```abstract``` and ```PFAM```. Optional fields are ```Sensor```, ```Activator``` and ```Effector```.
-
-[ ] Main title is correct.
-For a defense system, it should simply be the name of the system.
-
-[ ] All the information is provided, correct and understandable.
-Rule of thumb : As a newcommer in the field, does the page provide the essential information in a clear way regarding the system ?
-    [ ] Short description of the system
-    [ ] Composition of the system
-    [ ] Mechanism of action if it is known
-    [ ] References to the literature to further explore the defense system
-
-[ ] Links with the database are working.
-    [ ] Distribution of the system among prokaryotes
-    [ ] Structure display
-
-[ ] At least one relevant abstract is provided.
