+# Custom Roles
+
+Allows to manage custom roles (apart from the base roles) for chat interactions with the models.
+
+_Particularly helpful when you would need to use different roles that the newer models support other than the base
+roles._
+
+_Base roles are `SYSTEM`, `USER`, `ASSISTANT`, `TOOL`._
+
+### Usage
+
+#### Add new role
+
+```java
+import io.github.ollama4j.OllamaAPI;
+import io.github.ollama4j.models.chat.OllamaChatMessageRole;
+
+public class Main {
+
+    public static void main(String[] args) {
+        String host = "http://localhost:11434/";
+        OllamaAPI ollamaAPI = new OllamaAPI(host);
+
+        OllamaChatMessageRole customRole = ollamaAPI.addCustomRole("custom-role");
+    }
+}
+```
+
+#### List roles
+
+```java
+import io.github.ollama4j.OllamaAPI;
+import io.github.ollama4j.models.chat.OllamaChatMessageRole;
+
+public class Main {
+
+    public static void main(String[] args) {

+        OllamaAPI ollamaAPI = new OllamaAPI(host);
+
+        List<OllamaChatMessageRole> roles = ollamaAPI.listRoles();
+    }
+}
+```
+
+#### Get role
+
+```java
+import io.github.ollama4j.OllamaAPI;

+
+### List Models from Ollama Library
+
+This API fetches available models from the Ollama library page, including details such as the model's name, pull count,
+popular tags, tag count, and the last update time.
+
+```java title="ListLibraryModels.java"

+
+The following is the sample output:
+
+```

+
+### Pull model using `LibraryModelTag`
+
+You can use `LibraryModelTag` to pull models into Ollama server.
+
+```java title="PullLibraryModelTags.java"
