-This repo is a VPM package (`dev.av2x.aumss`) and requires the VRChat Worlds SDK 3.5.0 or newer.

+### ALCOM / VRChat Creator Companion
+
+1. Add this repository in ALCOM or VCC (in VCC: **Settings → Packages → Add Repository**):
+
+   ```
+   https://gogs.av2x.dev/av2x/AUMSS/raw/vpm/index.json
+   ```

+### Manual
+
+Clone the repo into your project's `Packages/dev.av2x.aumss` folder:
 
 ```
 git clone https://gogs.av2x.dev/av2x/AUMSS.git Packages/dev.av2x.aumss
 ```
 
-If the project already has the old `Artyom Scripting System` folder under `Assets`, delete it before adding the package. The package keeps the same script and program asset GUIDs, so existing scenes keep their references.
+A manual install doesn't get updates through ALCOM or VCC. Run `git pull` in that folder instead.
+
+### Upgrading from the old unitypackage
+
+Delete the old `Artyom Scripting System` folder from `Assets` before adding the package. The package uses the same script and program asset GUIDs, so existing scenes keep their references.
