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: 
contributors: 
  - Firstname Lastname
relevantAbstracts:
  - doi: my-doi
---

2. The following paragraphs - Description - Molecular mechanisms - Example of genomic structure - Distribution of the system among prokaryotes - Structure - Experimental validation - References with the following syntax : :ref{doi=my-doi}.

• 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
    • PFAM
  • Optional fields are :
    • Sensor
    • Activator
    • 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.
