-# nx-remotecache-custom
+# The future of `nx-remotecache-*`
+
+Nrwl Nx just introduced us to **Powerpack**. It's the clear successor of the remote cache setup and officially supports custom caching solutions. This will mark the end of the `nx-remotecache-*` packages as custom caching solutions based on the filesystem won't work anymore starting with Nx 21.
