 This store type is a variation of the [local store] designed to leverage Linux's [Overlay Filesystem](https://docs.kernel.org/filesystems/overlayfs.html) (OverlayFS for short).
 Just as OverlayFS combines a lower and upper filesystem by treating the upper one as a patch against the lower, the local overlay store combines a lower store with an upper almost-[local store].
-("almost" because while the upper fileystems for OverlayFS is valid on its own, the upper almost-store is not a valid local store on its own because some references will dangle.)
+("almost" because while the upper filesystems for OverlayFS is valid on its own, the upper almost-store is not a valid local store on its own because some references will dangle.)
 To use this store, you will first need to configure an OverlayFS mountpoint [appropriately](#example-filesystem-layout) as Nix will not do this for you (though it will verify the mountpoint is configured correctly).
