+# Empty Starter Kit for JavaScript
+
+[![Deploy to Fastly](https://deploy.edgecompute.app/button)](https://deploy.edgecompute.app/deploy)
+
+An empty application template for the Fastly Compute environment which returns a 200 OK response.
+
+**For more details about other starter kits for Compute, see the [Fastly developer hub](https://developer.fastly.com/solutions/starters)**
+
+## Running the application
+
+To create an application using this starter kit, create a new directory for your application and switch to it, and then type the following command:
+
+```shell
+npm create @fastly/compute@latest -- --language=javascript --starter-kit=empty
+```
+
+To build and run your new application in the local development environment, type the following command:
+
+```shell
+npm run start
+```
+
+To build and deploy your application to your Fastly account, type the following command. The first time you deploy the application, you will be prompted to create a new service in your account.
+
+```shell
+npm run deploy
+```
+
+## Security issues
+
+Please see our [SECURITY.md](SECURITY.md) for guidance on reporting security-related issues.

-# Empty Starter Kit for JavaScript
-
-[![Deploy to Fastly](https://deploy.edgecompute.app/button)](https://deploy.edgecompute.app/deploy)
-
-An empty application template for the Fastly Compute environment which returns a 200 OK response.
-
-**For more details about other starter kits for Compute, see the [Fastly developer hub](https://developer.fastly.com/solutions/starters)**
-
-## Running the application
-
-To create an application using this starter kit, create a new directory for your application and switch to it, and then type the following command:
-
-```shell
-npm create @fastly/compute@latest -- --language=javascript --starter-kit=empty
-```
-
-To build and run your new application in the local development environment, type the following command:
-
-```shell
-npm run start
-```
-
-To build and deploy your application to your Fastly account, type the following command. The first time you deploy the application, you will be prompted to create a new service in your account.
-
-```shell
-npm run deploy
-```
-
-## Security issues
