 ## Setup on LUMI-G
 Here is a step-by-step guide on installing packages on LUMI-G
 
-### Step 1: Install rocm-5.4.6 with Easybuild
-```
-export EBU_USER_PREFIX=/project/project_xxxxxx/EasyBuild
-ml LUMI/24.03 partition/G
-ml EasyBuild-user
-export PYTHONIOENCODING=utf-8
-eb rocm-5.4.6.eb -r
-```
-
-### Step 2: run conda-container
+### Step 1: run conda-container
 Installation via conda can be done as:
-```
+```shell
 ml LUMI/24.03 partition/G
-ml lumi-container-wrapper/0.3.3-cray-python-3.11.7
-```
+ml lumi-container-wrapper
 ```
+```shell
 conda-containerize new --prefix MyCondaEnv conda_environment_lumi.yml
 ```
 where the file `conda_environment_lumi.yml` contains packages to be installed.
 
-### Step 3: Set the env. variable to search for binaries
-```
-export the bin path: export PATH="$PWD/MyCondaEnv/bin:$PATH"
-```
-### An alternative: Convert to a singularity container with cotainr
+### Step 1 alternative: Convert to a singularity container with cotainr
 ```
 cotainr build my_container.sif --system=lumi-g --conda-env=conda_environment_lumi.yml
 ```
 
-### Error when running MPI.
+### Step 2: Modify Slurm Job file
+Update the contents of [`Jobs/job_lumi.slurm`](Jobs/job_lumi.slurm) to match your project allocation,
+and the directories of where the simulator and Conda container is stored.
+
+### Step 3: Run the Slurm Job
+```shell
+sbatch Jobs/job_lumi.slurm
+```
+
+### Troubleshooting
+
+#### Error when running MPI.
 ```
 `MPI startup(): PMI server not found. Please set I_MPI_PMI_LIBRARY variable if it is not a singleton case.
 ```
 This can be resolved by exporting this:
 ```
-export I_MPI_PMI_LIBRARY=/opt/cray/pe/mpich/8.1.27/ofi/cray/14.0/lib/libmpi.so
-```
-### Install hip-python
-```
-python -m pip install -i https://test.pypi.org/simple/ hip-python==5.4.3.470.16
-```
-
-The testing was done with this specific version `hip-python==5.4.3.470.16`
-
- 
+export I_MPI_PMI_LIBRARY=/opt/cray/pe/mpich/8.1.29/ofi/cray/17.0/lib/libmpi.so
