+# GitHub Pull Request Reviewer Action
+
+This repository contains a GitHub Action that automates the process of reviewing pull requests using OpenAI's GPT model.
+
+## Features
+
+- Fetches the diff of the changes when a pull request is opened or updated.
+- Submits the diff to the GPT model for review.
+- Posts the model's response as a comment on the pull request.
+
+## Usage
+
+To use this action in your GitHub workflows, add a step to your workflow file that references this repository:
+
+```yaml
+- name: Run PR Reviewer
+  uses: hdvinsurance/gpt-code-review-action@v1
+  with:
+    github_token: ${{ secrets.GITHUB_TOKEN }}
+    openai_api_key: ${{ secrets.OPENAI_API_KEY }}
+```
+
+## Inputs
+
+The action accepts the following inputs:
+
+- `github_token` (**required**): The GitHub token used to post comments on the pull request. This is a required input.
+
+- `openai_api_key`: The OpenAI API key. This is required if the `OPENAI_API_KEY` environment variable is not set. This input is optional.
+
+- `pr_review_prompt_template`: Provide a PR review prompt template to optionally override the default prompt template with your own. This input is optional and defaults to an empty string.
+
+- `model_name`: Optional. Defaults to `gpt-3.5-turbo-16k`.
+
+## Outputs
+
+The action produces the following output:
+
+- `pr_review`: The PR review text. Note: this is the raw output from the GPT model and may contain newlines and other formatting characters.
+
+## Considerations and Limitations
+
+Code Reviews performed by a generative AI process may not always be correct. Exercise caution when evaluating the suggestions of the model.
