+# Custom Planets Sky
+
+Now that you have your beautiful planets registered, your planet need to have a beautiful sky !
+
+## Creation of the Resourcepack
+
+First, you'll need to create the base of the resourcepack. The structure of the resourcepack should look like this :
+
+```
+├─ assets
+│  └─ [namespace]
+│     └─ renderer
+│         └─ sky
+│
+└─ pack.mcmeta
+```
+
+::: tip
+`[namespace]` should be the same as your datapack
+:::
+
+
+**The sky folder**
+This folder will contains all of the custom skies for our planets.
+
+```json
