+## Setting the API Endpoint
+
+You can set the API Endpoint for accessing the ollama API using either a command line argument or an environment variable.
+
+### Using Command Line Argument
+
+To set the API Endpoint using a command line argument, run the program with the API Endpoint as the first argument:
+
+```sh
+go run main.go <API_ENDPOINT>
+```
+
+Replace `<API_ENDPOINT>` with the actual API Endpoint URL.
+
+### Using Environment Variable
+
+To set the API Endpoint using an environment variable, set the `OLLAMA_API_ENDPOINT` environment variable before running the program:
+
+```sh
+export OLLAMA_API_ENDPOINT=<API_ENDPOINT>
+go run main.go
+```
+
+Replace `<API_ENDPOINT>` with the actual API Endpoint URL.
