-And register it:
+We're going to need to register our ''BlockEntityRenderer'', but only for the client.
+This wouldn't matter in a single-player setting, since the server runs in the same process as the client.
+However, in a multiplayer setting, where the server runs in a different process than the client, the server code
+has no concept of a "BlockEntityRenderer", and as a result would not accept registering one.
+To run initialization code only for the client, we need to setup a ''client'' entrypoint.
+Create a new class next to your main class that implements ''ClientModInitializer'':
 <code java>
-@Override
+public class ExampleModClient implements ClientModInitializer {
-public void onInitialize() {
+    @Override
+    public void onInitializeClient() {
+        // Here we will put client-only registration code
+    }
+}
+</code>
+Set this class as the ''client'' entrypoint in your ''fabric.mod.json'' (modify the path as needed):
+<code javascript "fabric.mod.json">
+"entrypoints": {
     [...]
+    "client": [
+      {
+        "value": "tutorial.path.to.ExampleModClient"
+      }
+    ]
+}
+</code>
+And register the ''BlockEntityRenderer'' in our ClientModInitializer:
+<code java>
+@Override
+public void onInitializeClient() {
     BlockEntityRendererRegistry.INSTANCE.register(DemoBlockEntity.class, new MyBlockEntityRenderer());
 }
