-Previously, `params` for `routes/route` were calculated as `{ p: string, r: string }`.
+Previously, `params` for the `routes/layout.tsx` route were calculated as `{ p: string, l: string }`.
 This incorrectly ignores params that could come from child routes.
-If visiting `/parent/1/route/2/child1/3/4`, the actual params passed to `routes/route` will have a type of `{ p: string, r: string, c1a: string, c1b: string }`.
+If visiting `/parent/1/layout/2/child1/3/4`, the actual params passed to `routes/layout.tsx` will have a type of `{ p: string, l: string, c1a: string, c1b: string }`.
 
 Now, `params` are aware of child routes and autocompletion will include child params as optionals:
 
 ```ts
 params.|
 //     ^ cursor is here and you ask for autocompletion
 // p: string
-// r: string
+// l: string
 // c1a?: string
 // c1b?: string
 // c2a?: string
 // c2b?: string
 ```
 
-You can also narrow the types for `params` as it is implemented as a normalized union of params for each page that includes `routes/route`:
