+# InfectedRose.Interface
+
+This is a modding interface for LEGO® Universe.
+
+## Setup
+
+In the client, create a `mods` directory, than create a `mods.json` file in that directory:
+```json
+{
+  "database": "cdclient.fdb",
+  "sqlite": "CDServer.sqlite"
+}
+```
+Copy over `res/cdclient.fdb` directory into `mods` directory, this will be the database the interface works upon.
+
+When the interface is run, it will save to`res/cdclient.fdb`, the database in the `mods` directory will remain contant.
+
+The interface will also save the database converted to SQLite,
+the `sqlite` entry in the `mods.json` file can be changed to point to where the server loads it.
+
+## Running
+
+```bash
+# Apply mods (-i can be excluded if exectued from where mods.json is located)
+dotnet InfectedRose.Interface.dll -i <path-to-mods.json>
+
+# Copy an object into a mod file
+dotnet InfectedRose.Interface.dll -c <lot> -d <my-mod:id> -o <output-mod.json>
+```
+
+## Mods
+
+In the `mods` directory can subdirectories be created, each containing a `manifest.json`:
+```json
+{
+    "name": "My Mods",
+    "files": [
+        "npc/mod.json"
+    ]
+}
+```
+
+Each subdirectory with a `manifest.json` will be loaded by the interface.
+
+The `files` entry specifies paths to json files where the details of the mod is specified.
+
+## Creating mods
+
+An example of a mod file:
+```json
+# mod.json
+[
+  {
+    "id": "my-mod:brick",
+    "type": "object",
+    "action": "add",
+    "components": [
+      "my-mod:render-component:brick",
+      "my-mod:simple-physics-component:brick"
+    ],
+    "values": {
+      "name": "my brick!",
+      "type": "Environmental"
+    }
+  },
+  {
+    "id": "my-mod:render-component:brick",
+    "type": "RenderComponent",
+    "action": "add",
+    "values": {
+      "render_asset": "ASSET:assets/brick.nif",
+      "shader_id": 1
+    }
+  },
+  {
+    "id": "my-mod:simple-physics-component:brick",
+    "type": "SimplePhysicsComponent",
+    "action": "add",
+    "values": {
+      "static": 1,
+      "physics_asset": "ASSET:PHYSICS:assets/brick.hkx"
+    }
+  }
+]
+```
+
+This will create an object with two components, a RenderComponent and a SimplePhysicsComponent.
+
+Values starting with `ASSET:` will be formatted to a path the game will use to find files included in the mod.
+
+In this example a `assets` subdirectory was created in the same directory where `mod.json` is located, where the mod includes two assets.
+The resulting path to the asset will be `..\\mods\\my-mod\\brick\\assets\\brick.nif`. 
+
+Additionally `PHYSICS:` can be appended for when the path has to originate from `res/physics`.
