Terraria Wiki:Style guide/Biome

Here you put the "Biome banner" (ex. )

Here you write description about biome and be sure to include main blocks and spawn's (ex. The landscape of a forest includes lots of grass, plenty of trees, several lakes ranging from small to large and, sometimes, Sunflowers. Dayblooms and Pumpkins can be found growing in this biome.)

Also (if it's possible) you can include releated underground biome

(ex. Underneath the Snow biome you will find the Underground Snow )

Next thing that is important is Template:Biome.
