+# What is DCS Liberation Campaign?
 
-Important: [Code of Conduct](Code-of-Conduct)
+In it's essence, it's a DCS mission generator, consisting of the following building blocks:
 
-It's recommended to read the [Getting Started](Getting-started) guide first.
+- [Campaigns](Custom-campaigns)
+- [Factions](Custom-Factions) 
+- [Squadrons](Squadrons-and-pilots)
 
+The campaign acts as a template, populated by units available, based on the factions and timeline chosen and generates a new mission (liberation_nextturn.miz) every time you hit the *launch* button in the UI.
+
+Once a mission has ended, DCS Liberation captures the events (state) that happend in DCS and processes them, so that the player can make adjustments and hit *launch* again.
+
+This pattern provides a custom, dynamic and persistent campaign.
+
+
+For more information, it's recommended to read the [Getting Started](Getting-started) guide first.
