-[GNU Guix](https://guix.gnu.org) is a distribution of the GNU operating system but also a package manager. You can use it to create bit-by-bit reproducible (Linux) binaries of `ogs`. The package definitions are defined in [`guix.scm`](https://gitlab.opengeosys.org/ogs/ogs/-/blob/master/guix.scm). `guix` is currently installed on `envinf3`.
+[GNU Guix](https://guix.gnu.org) is a distribution of the GNU operating system but also a package manager. You can use it to create bit-by-bit reproducible (Linux) binaries of `ogs`.
+
+The package definitions for OGS are defined in [this repo](https://gitlab.opengeosys.org/ogs/inf/guix-ogs) which can be used as a Guix channel. `guix` is currently installed on `envinf3`.
 
 ## Building
 
+### From local source tree
+
+```bash
+# builds ogs serial config
+guix time-machine -C scripts/guix/channels.scm -- \
+  build ogs --with-source=ogs@6.4.4-testing=$PWD
+# SteadyStateDiffuion process only:
+guix time-machine -C scripts/guix/channels.scm -- \
+  build ogs-ssd --with-source=ogs-ssd@6.4.4-testing=$PWD
+# ogs petsc config
+guix time-machine -C scripts/guix/channels.scm -- \
+  build ogs-petsc --with-source=ogs-petsc@6.4.4-testing=$PWD
+```
+
+The version string starting after `@` can be set individually. To get the dependency tree:
+
+```bash
+guix time-machine -C scripts/guix/channels.scm -- graph ogs | dot -Tpdf > dag.pdf
+```
+
+### From web URL
+
 ```bash
-guix build -f guix.scm                     # builds ogs serial config
-guix build -L $PWD/.guix/modules ogs-ssd   # SteadyStateDiffuion process only
-guix build -L $PWD/.guix/modules ogs-petsc # ogs petsc config
+wget https://gitlab.opengeosys.org/ogs/ogs/-/raw/master/scripts/guix/channels.scm
+guix time-machine -C ./channels.scm -- build ogs \
+  --with-source=ogs@6.4.4-testing=https://gitlab.opengeosys.org/ogs/ogs/-/archive/master/ogs-master.tar.bz2
 ```
 
 ## Developing
 
 ```bash
-guix shell
+guix time-machine -C scripts/guix/channels.scm -- \
+  shell --container --nesting --network --development ogs \ # OR ogs-petsc
+  openssl nss-certs coreutils bash git
 # Now in guix shell with all dependencies installed:
 export CMAKE_PRESET_BUILD_DIR_PREFIX=guix/ # presets then create e.g. ../build/guix/release
 cmake --preset release -DOGS_BUILD_PROCESSES=SteadyStateDiffusion
 cmake --build --preset release
 ```
 
+As a shortcut you can use this script:
+
+```bash
+./scripts/guix/ogs-env.sh ogs # for serial or `ogs-petsc` for parallel
+```
+
+You can also play with e.g. different versions of dependencies, here changing OpenMPI to 4.1.6:
+
+```bash
+guix time-machine -C scripts/guix/channels.scm -- \
+  shell --container --nesting --network --development ogs-petsc \
+  openssl nss-certs coreutils bash git \
+  --with-source=openmpi@4.1.6=https://download.open-mpi.org/release/open-mpi/v4.1/openmpi-4.1.6.tar.bz2
+```
