 # SM-DLM
 A dll that adds custom audio support for Scrap Mechanic mods
 
-# Goals
-- Add a sound config file for each mod
-- Make sounds reloadable
+# How to use
+- Create `sm_dlm_config.json` in the root directory of your mod.
+- An example of how `sm_dlm_config.json` structure should look like.
+```jsonc
+{
+  //Make the names more unique to avoid name collisions with other mods
+  "soundList": {
+    //You can reference the same sound multiple times, but configure them differently
+    "ExampleSoundName": {
+      "path": "$CONTENT_DATA/CustomAudio/1_2_Oatmeal.mp3",
+      "is3D": true
+    },
+    "ExampleSoundName2": {
+      "path": "$CONTENT_DATA/CustomAudio/1_2_Oatmeal.mp3",
+      "is3D": false
+    }
+  }
+}
+```
+- The names specified in `sm_dlm_config.json` can then be used in effects!
+```json
+"ExampleEffect": {
+  "effectList": [
+    {
+      "type": "audio",
+      "name": "ExampleSoundName1"
+    }
+  ]
+}
+```
