+## Supported Platforms
+
+| Platform          | Module                 | Java Version | Adventure API         | Status                 |

+| **Core**          | `multification-core`   | Java 8+      | Custom implementation | ✅ For custom platforms |
+
+> **💡 Recommendation:** Use `multification-paper` for Paper servers (1.19.4+) to leverage native Adventure API without
+> external dependencies.
+
 ## Getting Started
 
-To use the library, you need to add the following repository and dependency to your `build.gradle` file:
+### For Paper Servers (Recommended)
+
+Add the following repository and dependency to your `build.gradle.kts`:
 
 ```kts
-maven("https://repo.eternalcode.pl/releases")
+repositories {
+    maven("https://repo.eternalcode.pl/releases")
+    maven("https://repo.papermc.io/repository/maven-public/")
+}
+
+dependencies {
+    implementation("com.eternalcode:multification-paper:1.2.3")
+}
 ```
 
+### For Bukkit/Spigot Servers
+
 ```kts
-implementation("com.eternalcode:multification-bukkit:1.2.2")
+repositories {
+    maven("https://repo.eternalcode.pl/releases")
+}
+
+dependencies {
+    implementation("com.eternalcode:multification-bukkit:1.2.3")
+}
 ```
 
-> **Note:** If you want to use the library with other platforms, then you need to use the `multification-core` dependency.
+> **Note:** For custom platforms or other Adventure-based servers, use `multification-core` and implement your own
+> platform adapter.
