+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be

+# Sample GitHub App
+
+# Super lazy coder
+
+This sample app showcases how webhooks can be used with a GitHub App's installation token to create a bot that responds to issues. Code uses [octokit.js](https://github.com/octokit/octokit.js).
+
+## Requirements
+
+- Node.js 20 or higher
+- A GitHub App subscribed to **Pull Request** events and with the following permissions:
+  - Pull requests: Read & write
+  - Metadata: Read-only
+- (For local development) A tunnel to expose your local server to the internet (e.g. [smee](https://smee.io/), [ngrok](https://ngrok.com/) or [cloudflared](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/local/))
+- Your GitHub App Webhook must be configured to receive events at a URL that is accessible from the internet.
+
+## Setup
+
+1. Clone this repository.
+2. Create a `.env` file similar to `.env.example` and set actual values. If you are using GitHub Enterprise Server, also include a `ENTERPRISE_HOSTNAME` variable and set the value to the name of your GitHub Enterprise Server instance.
+3. Install dependencies with `npm install`.
+4. Start the server with `npm run server`.
+5. Ensure your server is reachable from the internet.
+    - If you're using `smee`, run `smee -u <smee_url> -t http://localhost:3000/api/webhook`.
+6. Ensure your GitHub App includes at least one repository on its installations.
+
+## Usage
+
+With your server running, you can now create a pull request on any repository that
+your app can access. GitHub will emit a `pull_request.opened` event and will deliver
+the corresponding Webhook [payload](https://docs.github.com/webhooks-and-events/webhooks/webhook-events-and-payloads#pull_request) to your server.
+
+The server in this example listens for `pull_request.opened` events and acts on
+them by creating a comment on the pull request, with the message in `message.md`,
+using the [octokit.js rest methods](https://github.com/octokit/octokit.js#octokitrest-endpoint-methods).
+
+## Security considerations
+
+To keep things simple, this example reads the `GITHUB_APP_PRIVATE_KEY` from the
+environment. A more secure and recommended approach is to use a secrets management system
+like [Vault](https://www.vaultproject.io/use-cases/key-management), or one offered
+by major cloud providers:
+[Azure Key Vault](https://learn.microsoft.com/en-us/azure/key-vault/secrets/quick-create-node?tabs=windows),
+[AWS Secrets Manager](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-secrets-manager/),
+[Google Secret Manager](https://cloud.google.com/nodejs/docs/reference/secret-manager/latest),
+etc.

+Thanks for helping make GitHub safe for everyone.
+
+# Security
+
+GitHub takes the security of our software products and services seriously, including all of the open source code repositories managed through our GitHub organizations, such as [GitHub](https://github.com/GitHub).
+
+Even though [open source repositories are outside of the scope of our bug bounty program](https://bounty.github.com/index.html#scope) and therefore not eligible for bounty rewards, we will ensure that your finding gets passed along to the appropriate maintainers for remediation. 
+
+## Reporting Security Issues
+
+If you believe you have found a security vulnerability in any GitHub-owned repository, please report it to us through coordinated disclosure.
+
+**Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.**
+
+Instead, please send an email to opensource-security[@]github.com.
+
+Please include as much of the information listed below as you can to help us better understand and resolve the issue:
+
+  * The type of issue (e.g., buffer overflow, SQL injection, or cross-site scripting)
+  * Full paths of source file(s) related to the manifestation of the issue
+  * The location of the affected source code (tag/branch/commit or direct URL)
+  * Any special configuration required to reproduce the issue
+  * Step-by-step instructions to reproduce the issue
+  * Proof-of-concept or exploit code (if possible)
+  * Impact of the issue, including how an attacker might exploit the issue
+
+This information will help us triage your report more quickly.
