+## OpenAI Integration
+LangChain Coder AI integrates with [OpenAI](https://openai.com/) to leverage its powerful machine learning models for code generation. OpenAI is an AI research and deployment company that aims to ensure that artificial general intelligence (AGI) benefits all of humanity. For more details on how LangChain integrates with OpenAI, refer to the [official documentation](https://python.langchain.com/docs/integrations/providers/openai).
+
+You need Open AI API **Key** to use LangChain Coder AI. To get your key, follow these steps:
+### Get OpenAI API key
+
+1. Go to the [OpenAI website](https://beta.openai.com/signup/).
+2. Fill out the form with your information and click “Create Account”.
+3. Once you are logged in, click on “API Keys” in the left-hand menu.
+4. Click on “Generate New Key” to create a new API key.
+5. Copy your API key – we will use it later in our Python code.

 ## Vertex AI Integration
 
 LangChain Coder AI integrates with [Google Vertex AI](https://cloud.google.com/python/docs/reference/aiplatform/latest) to leverage its powerful machine learning models for code generation. Vertex AI offers a range of tools and services for ML and AI, and LangChain Coder AI taps into these resources to provide top-notch code suggestions. For more details on how LangChain integrates with Vertex AI, refer to the [official documentation](https://python.langchain.com/docs/integrations/llms/google_vertex_ai_palm).
 
 Additionally, the Vertex AI SDK for Python allows for automation of data ingestion, model training, and predictions on Vertex AI. It provides a programmatic way to access most of the functionalities available in the Google Cloud console. For more information, check out the [Vertex AI SDK for Python](https://cloud.google.com/vertex-ai/docs/python-sdk/use-vertex-ai-python-sdk).
 
+You need Google Vertex **Service Account Credentials** to use LangChain Coder AI. To get your credentials, follow these steps:
+
+### Credentials for Google Vertex AI Service account and download JSON file
+
+1. Go to the [Google Cloud Platform Console](https://console.cloud.google.com/).
+2. Click the **Menu** button (three horizontal lines) in the top left corner of the page.
+3. Select **IAM & Admin** > **Service accounts**.
+4. Click the **Create Service Account** button.
+5. In the **Service account name** field, enter a name for your service account.
+6. Select the **Editor** role for the service account.
+7. Click the **Create** button.
+8. Click the **Keys** tab.
+9. Click the **Add Key** button.
+10. Select **JSON** as the key type.
