# Creating a simple LLM app To create your first LLM app, you'll need 3 things: credential, one LLM Node and one LLM Chain node. For the sake of this example, we'll make an app that uses ChatGPT. ### 1. Create New Chatbot Open the main menu and click on "Chatbots" -> "Create new chatbot"

### 2. Give it a name

### 3. Add a new node "ChatOpenAI" Click on the green floating button to add a new node, and search for "ChatOpenAI". Then, drag and drop it on the editor pane:

### 4. Set the credentials Click on "Change Parameters" button. It'll open the node's details where you will search for the [credentials you've created](/getting-started/adding-credentials.md) earlier. Then **Save Node Parameters**

Here you can also configure other parameters if you want

### 5. Add a "LLM Chain" node Click on the green floating button to add a new node, and search for "LLM Chain". Then, drag and drop it on the editor pane:

### 6. Connect the dots
