-### Build Target & Target Config
+### Build Target
 
 The following targets are supported: `browser` and `electron`. By default `browser` target is used.
 The target can be configured in the `package.json` via `theia/target` property, e.g:
 
+```json
+{
+    "theia": {
+        "target": "electron"
+    },
+    "dependencies": {
+        "@theia/electron": "latest"
+    }
+}
+```
+
+For `electron` target applications, is it mandatory to include **Electron** runtime dependencies. The `@theia/electron` package is the easiest way to install the necessary dependencies.
+
+### Target Config
+
+Application configuration for the frontend provides specific configurations for different target.There is an `electron` field configuration under `frontend.config` to configure the Electron target.The electron field currently supports the following configurations：
+- disallowReloadKeybinding：If set to `true`, reloading the current browser window won't be possible with the `Ctrl/Cmd + R` keybinding. It is `false` by default. Has no effect if not in an electron environment.
+- windowOptions：Override or add properties to the electron `windowOptions`.

 ### Using Latest Builds
 
 If you set `next` in your theia config, then Theia will prefer `next` over `latest` as the latest tag.
