 - Allow for splitting, you can now split your next app into multiple servers, which could each have their own configuration
 - An experimental bundled `NextServer` could be used which can reduce the size of your lambda by up to 24 MB
-- ~~Support for the `edge` runtime of next~~ (coming soon)
+- Support for the `edge` runtime of next (Only app router for now, only 1 route per function)
+
+## Get started
+
+The easiest way to get started is to use the [reference implementation construct](/v3/reference-implementation). Copy this reference implementation into your project and then use it like that in your sst or cdk project:
+
+```ts
+import { OpenNextCdkReferenceImplementation } from "path/to/reference-implementation"
+
+const site = new OpenNextCdkReferenceImplementation(stack, "site", {
+  openNextPath: ".open-next",
+})
+```
+
+You also need to create an `open-next.config.ts` file in your project root, you can find more info [here](/v3/config).
+
+A very simple example of this file could be:
+
+```ts
+import type { BuildOptions } from 'open-next/types/open-next'
+const config = {
+  default: {
+
+  }
+}
+module.exports = config
+```
+
+Then you need to run `npx [email protected] build` to build your project before running the `sst deploy` or `cdk deploy` command to deploy your project.
