+## How to create your own planets using configs:
+
+Coming soon
+
+There is a template [here](https://github.com/xen-42/ow-new-horizons-config-template) if you want to release your own planet mod using configs.
+
+## How to use New Horizons in other mods:
+
+First create the following interface in your mod:
+
+```
+public interface INewHorizons
+{
+    void Create(Dictionary<string, object> config);
+
+    void LoadConfigs(IModBehaviour mod);
+
+    GameObject GetPlanet(string name);
+}
+```
+
+In your main `ModBehaviour` class you can get the NewHorizons API like so:
+```
+INewHorizons NewHorizonsAPI = ModHelper.Interaction.GetModApi<INewHorizons>("xen.NewHorizons")
+```
+
+You can then use the API's `LoadConfigs()` method to load from a "planets" folder, or use the `Create()` and `GetPlanet` methods to create planets and do whatever with them. Just make sure you create planets in the `Start()` method or at least before the SolarSystem scene loads, or they will not be created.
