+# EventBus [![openupm](https://img.shields.io/npm/v/com.futuclass.event-bus?label=openupm&registry_uri=https://package.openupm.com)](https://openupm.com/packages/com.futuclass.event-bus/)
+
+
 EventBus is a system, which can dispatch published events to any registered handler accepting particular event argument. This means, that your event sources should no longer contain references to other components, only to event bus. 
 
 This creates a clean separation between event sources and handlers, and allows to build handler pipelines dynamically in runtime, rather than compile time. So in theory you can even load third-party libraries adopted for this Event Bus and insert their handlers into the pipeline. For example, this behavior can be used to implement plugin systems.
 
 ## Installation
-#### Using UnityPackageManager (for Unity 2018.3 or later)
-Find the manifest.json file in the Packages folder of your project and edit it to look like this:
-```js
-{
-  "dependencies": {
-    "com.futuclass.event-bus": "https://github.com/futuclass/EventBus.git",
-    ...
-  },
-}
+
+### Install via OpenUPM
+
+The package is available on the [openupm registry](https://openupm.com). It's recommended to install it via [openupm-cli](https://github.com/openupm/openupm-cli).
+
+```
+openupm add com.futuclass.event-bus
 ```
 
+### Install via Git URL
+
+Open *Packages/manifest.json* with your favorite text editor. Add the following line to the dependencies block.
+
+    {
+        "dependencies": {
+            "com.futuclass.event-bus": "https://github.com/Futuclass/EventBus.git"
+        }
+    }
+
+Notice: Unity Package Manager records the current commit to a lock entry of the *manifest.json*. To update to the latest version, change the hash value manually or remove the lock entry to resolve the package.
+
+    "lock": {
+      "com.futuclass.event-bus": {
+        "revision": "master",
+        "hash": "..."
+      }
+    }
