+Check out the supported
+options [here](https://github.com/jmorganca/ollama/blob/main/docs/modelfile.md#valid-parameters-and-values).
+
+## Build an empty Options object
+
+```java
+import io.github.amithkoujalgi.ollama4j.core.utils.Options;
+import io.github.amithkoujalgi.ollama4j.core.utils.OptionsBuilder;
+
+public class Main {
+
+    public static void main(String[] args) {
+
+        String host = "http://localhost:11434/";
+
+        OllamaAPI ollamaAPI = new OllamaAPI(host);
+
+        Options options = new OptionsBuilder().build();
+    }
+}
