+## Important Configuration Notes
+If you face any issues consider doing these:
+
+1. **JitPack Repository**
+   Use the following syntax for JitPack repository in your `build.gradle`:
+   ```gradle
+   allprojects {
+     repositories {
+       maven { url = uri("https://jitpack.io") }
+     }
+   }
+   ```
+
+2. **Java Version Configuration**
+   If you face Java-related issues, update your `android/app/build.gradle`:
+   ```gradle
+   android {
+     compileOptions {
+       sourceCompatibility = JavaVersion.VERSION_11
+       targetCompatibility = JavaVersion.VERSION_11
+     }
+   }
+   ```
+
+3. **Gradle Plugin Version**
+   Ensure you're using a compatible Gradle plugin version in your project's `build.gradle`:
+   ```gradle
+   buildscript {
+     dependencies {
+       classpath("com.android.tools.build:gradle:8.7.0")
+     }
+   }
+   ```
+
+4. **Kotlin Version**
+   Update the Kotlin version in your project's `build.gradle`:
+   ```gradle
+   buildscript {
+     ext.kotlin_version = "1.8.22"
+     // ...
+   }
+   ```
+
+## Troubleshooting
+
+If you encounter build issues, please verify:
+- All the above configurations are correctly set
+- Your project's Gradle version is compatible with the Android Gradle Plugin
+- You have Java 11 or later installed and properly configured in your environment
+
