+# biome-provider-pipeline-2
+
+The second version of the Biome Pipeline, a procedural biome provider that uses a series
+of "stages" to apply "mutations" to a 2D grid of biomes.
+
+Version 2 is a re-implementation of the original addon with the primary goal of providing
+consistent scaling for noise relative to the world
+(See https://github.com/PolyhedralDev/Terra/issues/264 for more details), and has been
+included as a separate addon to maintain parity with packs utilizing the first version. 
+
+This addon registers the `PIPELINE` biome provider type, and all associated
+configurations.
