+## Building your app automatically
+
+This extension will not build your App. If you would like to run a build each time a debug session is started, you can add a `preLaunchTask` option to your `launch.json` configuration which invokes a build task.
+
+#### .vscode/launch.json
+Add a `preLaunchTask` item to the launch configuration:
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "type": "android",
+            "request": "launch",
+            "name": "App Build & Launch",
+            "preLaunchTask": "run gradle",
+        }
+    ]
+}
+```
+Add a new task to run the build command:
+#### .vscode/tasks.json
+```json
+{
+    "version": "2.0.0",
+    "tasks": [
+        {
+            "label": "run gradle",
+            "type": "shell",

+}

+## Powered by coffee
+
+The Android Developer Extension is a completely free, fully open-source project. If you've found the extension useful, you
+can support it by [buying me a coffee](https://www.buymeacoffee.com/adelphes).
+
+If you use ApplePay or Google Pay, you can scan the code with your phone camera:
+
+![BuyMeACoffee Code](https://raw.githubusercontent.com/adelphes/android-dev-ext/master/images/bmac-code.png)
