 > - `revalidatePath` is available in both [Node.js and Edge runtimes](/docs/app/building-your-application/rendering/edge-and-nodejs-runtimes).
-> - `revalidatePath` will revalidate _all segments_ under a dynamic route segment. For example, if you have a dynamic segment `/product/[id]` and you call `revalidatePath('/product/[id]')`, then all segments under `/product/[id]` will be revalidated as requested.
-> - `revalidatePath` only invalidates the cache when the path is next visited. This means calling `revalidatePath` with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited.
+> - `revalidatePath` can invalidate by:
+>   - URL `revalidatePath('/blog/post-1')` invalidates just this specific URL
+>   - page path `revalidatePath('/blog/[slug]', 'page')` invalidates the page regardless of exact URL
+>   - from a layout `revalidatePath('/blog/[slug]', 'layout')` invalidates any paths that include this layout
+> - `revalidatePath` only invalidates the cache when the included path is next visited. This means calling `revalidatePath` with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited.
 
 ## Parameters
 
 ```tsx
-revalidatePath(path: string): void;
+revalidatePath(path: string, type?: 'page' | 'layout'): void;
 ```
 
-- `path`: A string representing the filesystem path associated with the data you want to revalidate. This is **not** the literal route segment (e.g. `/product/123`) but instead the path on the filesystem (e.g. `/product/[id]`).
+- `path`: A string representing the filesystem path associated with the data you want to revalidate. This is the literal route segment (e.g. `/product/123`) not the path on the filesystem `/product/[slug]/page`.
+- `type`: An optional string of either 'page' or 'layout' to change behavior of what type of path is being revalidated.
