+# OpenAI GPT-3 Chat Completion Function
+
+**Warning:** This function uses the OpenAI API, which is a paid service. You will be charged for each request made to the API. For more information, see the [OpenAI pricing page](https://openai.com/pricing/).
+
+This function enables the interaction with OpenAI's GPT-3 model in a chat-like format. Users send a request with a prompt and receive a text response generated by the model. Additionally, there's a simple GET endpoint that serves an HTML page.
+
+## Environment Variables
+
+To ensure the function operates as intended, ensure the following variables are set:
+
+- **OPENAI_API_KEY**: This is your OpenAI API key.
+- **OPENAI_MAX_TOKENS**: This is the maximum number of tokens that the OpenAI response should contain. Be aware that OpenAI models read and write a maximum number of tokens per API call, which varies depending on the model. For GPT-3.5-turbo, the limit is 4096 tokens.
+
+## Usage
+
+This function supports two types of requests:
+
+1. **Serving the HTML page**
+
+   - **Request Type:** GET
+   - **Response:** 
+     - On success, the function will respond with the HTML file contained in the static folder.
+
+2. **Interacting with the GPT-3 Model**
+
+   - **Request Type:** POST
+   - **Body:** 
+     - The text string that is used as a prompt for the model.
+   - **Response:** 
+     - On success, the function will respond with the text generated by the GPT-3 model.
+     - If the request body is missing, a 400 error will be returned with the message 'Missing body with a prompt.'
+
+## Example
+
+Here's a simple example of how to use the POST endpoint:
+
+**Request:**
+
+```
+POST / HTTP/1.1
+Host: function-host
+Content-Type: text/plain
+
+"What is the weather like today?"
+```
+
+**Response:**
+
+```json
+{
+  "role": "assistant",
+  "content": "As an AI model, I don't have real-time data capabilities, so I'm unable to provide the current weather. However, you can check a reliable weather website or app for this information."
+}
+```
+
+Note: The response can vary as it is generated by the AI model based on the input prompt.

-# OpenAI GPT-3 Chat Completion Function
+# ⚡ OpenAI ChatGPT Function
 
-**Warning:** This function uses the OpenAI API, which is a paid service. You will be charged for each request made to the API. For more information, see the [OpenAI pricing page](https://openai.com/pricing/).
+Query the OpenAI GPT-3.5-turbo model for chat completions.
 
-This function enables the interaction with OpenAI's GPT-3 model in a chat-like format. Users send a request with a prompt and receive a text response generated by the model. Additionally, there's a simple GET endpoint that serves an HTML page.
+## 🧰 Usage
 
-## Environment Variables
+### `GET`
 
-To ensure the function operates as intended, ensure the following variables are set:
+HTML form for interacting with the model.
 
-- **OPENAI_API_KEY**: This is your OpenAI API key.
-- **OPENAI_MAX_TOKENS**: This is the maximum number of tokens that the OpenAI response should contain. Be aware that OpenAI models read and write a maximum number of tokens per API call, which varies depending on the model. For GPT-3.5-turbo, the limit is 4096 tokens.
+### `POST`
 
-## Usage
+Query the model for a completion.
 
-This function supports two types of requests:
+**Parameters**
 
-1. **Serving the HTML page**
+| Name | Description              | Location | Type   | Sample Value                  |
+| ---- | ------------------------ | -------- | ------ | ----------------------------- |
+| N/A  | Text to prompt the model | Body     | String | `Write a haiku about Mondays` |
 
-   - **Request Type:** GET
-   - **Response:** 
-     - On success, the function will respond with the HTML file contained in the static folder.
+Sample `200` Response:
 
-2. **Interacting with the GPT-3 Model**
+Response from the model.
 
-   - **Request Type:** POST
-   - **Body:** 
-     - The text string that is used as a prompt for the model.
-   - **Response:** 
-     - On success, the function will respond with the text generated by the GPT-3 model.
-     - If the request body is missing, a 400 error will be returned with the message 'Missing body with a prompt.'
-
-## Example
+```text
+Monday's heavy weight,
+Dawning with a sigh of grey,
+Hopeful hearts await.
+```
 
-Here's a simple example of how to use the POST endpoint:
+Sample `400` Response:
 
-**Request:**
+Response when the request body is missing.
 
 ```
-POST / HTTP/1.1
-Host: function-host
-Content-Type: text/plain
-
-"What is the weather like today?"
+Missing body with a prompt.
 ```
 
-**Response:**
+## ⚙️ Configuration
 
-```json
-{
-  "role": "assistant",
-  "content": "As an AI model, I don't have real-time data capabilities, so I'm unable to provide the current weather. However, you can check a reliable weather website or app for this information."
-}
-```
