+#### Android Studio Configuration
+
+This project generates large Kotlin files that exceed Android Studio's default indexing limits. Add the following VM option to enable proper code indexing:
+
+```
+-Didea.max.intellisense.filesize=999999
+```
+
+To add this:
+1. Go to `Help` > `Edit Custom VM Options`
+2. Add the line to the `studio.vmoptions` file
+3. Invalidate caches and restart Android Studio
+
+This setting helps resolve indexing issues with large generated files like `wp_api.kt`.
+
+**Troubleshooting:** If Android Studio cannot find `cargo`, it may be using its internal JDK instead of the system one. To fix this, [switch Android Studio to use your system JDK](https://stackoverflow.com/questions/30631286/how-to-specify-the-jdk-version-in-android-studio).
