+title: Community
+---
+
+We are thankful for the community surrounding the Toolkit.
+
+Here are some links with respect to two types of community involvement:
+
+1. Addons to the code
+1. Content about the Toolkit
+1. Discord
+
+## Addons
+
+### ngrx-toolkit-openapi-gen
+
+[Murat Sari](https://github.com/wolfmanfx) created an OpenAPI generator that creates:
+
+✅ an NgRx Signal Store
+
+✅ with Resources
+
+✅ and Mutations
+
+✅ based on a Zod schema
+
+[Check it out here](https://www.npmjs.com/package/ngrx-toolkit-openapi-gen)
+
+## Content
+
+- Zoaib Khan
+  - [Blog post: "Use withResource to seamlessly combine Resources with Ngrx Signals Store!"](https://zoaibkhan.com/blog/use-withresource-to-seamlessly-combine-resources-with-ngrx/)
+  - [YouTube short: "Local Storage Sync with Ngrx Signal Store"](https://www.youtube.com/shorts/wbRxCCUrGvk)
+- Angular Space livestreams
+  - [Rainer's appearance](https://youtu.be/UUhZm52tigQ?t=2930), taking general Toolkit questions from Angular Space host Armen Vardanyan
+  - [Michael Small's appearance](https://youtu.be/X59d8GJnNhE?t=603), speaking about Mutations when they were being RFC'd, and `withResource`.
+- [Jason Warner (@xocomil) speaks about `withResource/withMutations` on a livestream](https://www.youtube.com/watch?v=kitcmXNj5K0&t=6344s)
+  - Michael Small is an active chat member on Jason's streams, so Jason has talked about the Toolkit a lot on stream, and probably will in the future if he keeps humoring Michael.
+
+## Discord
+
+Community contributions are sometimes shared on our Discord. [Link to join the NgRx Toolkit Discord](https://discord.gg/xnkSWDmpXZ). Feel free to share your Toolkit related content there, as well as any general discussion that may not fit cleanly under a GitHub issue or discussion post.
