- Adding more specific example of using output of query response in a reactive context
- How to invalidate queries as it's different than trpc docs

+## Output
+To use the output of the query, you must remember to **not** destructure elements. Doing so violates the reactivity of the query result. This principle is general to Solid, please read more here https://github.com/solidjs/solid/discussions/408#discussioncomment-628486.

+## Query Invalidation
+To invalidate queries, please see the following example of using `utils` which come as part of the `trpc` object you created through `createTRPCSolid.`
+
+```ts
+// navbar.tsx
+const queryRes = trpc.example.hello.useQuery(name()); // ✅
+
+const Navbar = () => {
+  return <div>{queryRes.data}</div>;

+  const sayHelloAgain = () => {
+    trpcUtils.example.hello.invalidate()
+  }
+  
+  return <button onClick={sayHelloAgain}>say hello again</div>;
