+### Sharing data
+It is better practice to define common entries/rules in a single file to get them from any army catalogue and to easily maintain it without duplicate oddities.
+* Common model between armies defined in a single original catalogue (eg. Mercenary) and included in another with a catalogueLink. 
+* Model's special rules in the game system's shared rules section.   
+* Weapon rules in their corresponding army catalogue's shared rules section. If you notice this weapon's rule is shared between armies, then define it in game system's shared rules.
+* Theme force rules in their corresponding army catalogue's shared rules section.
