+To run the verification tasks for the sorting network (unbounded proofs with variable numbers of lanes), change directory to the root of this project, set up the [Nix](https://nixos.org) environment by running `nix-shell` and do
 
 ```bash
 $ python -m rtio.test.sed.output_network
 ```
 
-## Progress
+This should complete in under an hour. The time to complete each verification task (2 lanes, 4 lanes, 8 lanes) is printed to standard output.
