 ## deploy
 
 The deployment of the live version of the interface is handled by code in the
 [`deploy`](https://github.com/katrinafyi/aslp-web/tree/deploy)
 branch of this repository.

-This contains scripts to reproducibly build multiple versions of the aslp-web interface
-(so links to aslp-web output are reproducible and permanent).
-This is done by building pinned versions of aslp-web and aslp from the [pac-nix](https://github.com/katrinafyi/pac-nix)
-repository.
-
-The build can be run using `./build.py`.
-Deployment is done by GitHub actions using this same script.
