In this document we +explain the GeneNetwork version 2 (GN2) reproducible deployment system +which is based on GNU Guix (see also Pjotr's [[https://github.com/pjotrp/guix-notes/blob/master/README.md][Guix-notes]]). The Guix +system can be used to install GN with all its files and dependencies. -* Binary deployment +The official installation path is from a checked out version of the +main Guix package tree and that of the Genenetwork package +tree. Current supported versions can be found as the SHA values of +'gn-latest' branches of [[https://github.com/genenetwork/guix-bioinformatics/tree/gn-latest][Guix bioinformatics]] and [[https://github.com/genenetwork/guix/tree/gn-latest][GNU Guix main]]. -NYA +* Source deployment +** Install guix -* From source deployment +Deploying from source is also straightforward.
