+## Migrating to eslint-config-node
+
+TypeScript ESLint support is now built directly into [`@hs-web-team/eslint-config-node`](https://www.npmjs.com/package/@hs-web-team/eslint-config-node) — you no longer need a separate TypeScript config package.
+
+> **Note:** If your project also uses `@hs-web-team/eslint-config-browser`, that package is also deprecated. The replacement is the `/browser` export from `@hs-web-team/eslint-config-node`.
+
+Follow these steps to migrate, or see [MIGRATION-V3.md](https://github.com/HubSpotWebTeam/wt-eslint-node/blob/main/docs/MIGRATION-V3.md) for the full guide:
+
+### For Node.js projects
+
+```sh
+npm uninstall @hs-web-team/eslint-config-ts
+npm install -D @hs-web-team/eslint-config-node@latest
+```
+
+```js
+// eslint.config.mjs
+import wtConfig from '@hs-web-team/eslint-config-node';
+
+export default [
+  ...wtConfig,
+];
+```
+
+### For browser/React projects
+
+```sh
+npm uninstall @hs-web-team/eslint-config-browser @hs-web-team/eslint-config-ts
+npm install -D @hs-web-team/eslint-config-node@latest
+```
+
+```js
+// eslint.config.mjs
+import wtBrowserConfig from '@hs-web-team/eslint-config-node/browser';
+
+export default [
+  ...wtBrowserConfig,
