+## UnityOpus 🔉
 Note: A UPM fork of [UnityOps by TyounanMOTI](https://github.com/TyounanMOTI/UnityOpus) with some XML comments. The original project is sponsored by Cluster, Inc.

+## Installation 📦
+Ensure you have the NPM registry in the `packages.json` file of your Unity project with `com.adrenak.unityops` as one of the scopes
+```
+"scopedRegistries": [
+    {
+        "name": "npmjs",
+        "url": "https://registry.npmjs.org",
+        "scopes": [
+            "com.npmjs",
+            "com.adrenak.unityopus"
+        ]
+    }
+}
+```
+
+Add `"com.adrenak.unityopus" : "x.y.z"` to `dependencies` list in `packages.json` file where `x.y.z` is the version name
+
+## Tip
+The [Encoder.Encode](https://www.vatsalambastha.com/UnityOpus/api/Adrenak.UnityOpus.Encoder.html#Adrenak_UnityOpus_Encoder_Encode_System_Single___System_Byte___0) returns an int.  
+If it's > 0, encoding succeeded and this int represents the length of the encoded audio in the output array. You'll need to copy the encoded audio from the output.  
+If it's < 0, encoding has failed and the int actually represents the error code
+
+```
+// Assuming pcm is the float[] you want to encode
+// The output array should be equal to the pcm array size in bytes, hence multuplied by 4
+byte[] output = new byte[pcm.Length * 4];
+int encodeResult = encoder.Encode(pcm, output); 
+if(encodedResult > 0) {
+    byte[] encodedBytes = new byte[encodeResult];
+    Array.Copy(encodeBuffer, encodedBytes, encodedBytes.Length);
+    // encodedBytes now has the encoded audio ready for your use
+}
+else {
+    // Get the error
+    ErrorCode errorCode = (ErrorCode)encodeResult;
+}
+
+```
