-Migrating the Tech Radar to support using `ApiRefs` to go fetch data
+Migrating the Tech Radar to support using `ApiRefs` to load custom data.
+
+If you had a `getData` function, you'll now need to encapsulate that logic in a class that can override the `techRadarApiRef`.
+
+```ts
+// app/src/lib/MyClient.ts
+import {
+  TechRadarApi,
+  TechRadarLoaderResponse,
+} from '@backstage/plugin-tech-radar';
+
+class MyOwnClient implements TechRadarApi {
+  async load(): Promise<TechRadarLoaderResponse> {
+    // here's where you would put you logic to load the response that was previously passed into getData
+  }
+}
+
+// app/src/apis.ts
+import { MyOwnClient } from './lib/MyClient';
+import { techRadarApiRef } from '@backstage/plugin-tech-radar';
+
+export const apis: AnyApiFactory[] = [
+  /*
+  ...
+  */
+  createApiFactory(techRadarApiRef, new MyOwnClient()),
+];
+```
