+To use use the OpenMPI compilers (mpicc, mpic++, etc.) and mpirun
+on Fedora, you'll need to install the openmpi package as well
+as set up the envionrment paths correctly.
+
+To install:
+```bash
+sudo dnf install openmpi
+```
+
+Then to set up the environmental variables correctly
+so that PATH is set. You'll need to use the
+[environment modules](https://modules.readthedocs.io/en/latest/)
+program installed by default on Fedora. First, you'll
+need to source it:
+```bash
+source /etc/profile.d/modules.sh
+```
+
+Now you can load in the OpenMPI module
+```bash
+module load mpi/openmpi-x86_64
+```
+
+Finally, with these changes you can use the compiler
+tools and runner. Do note that you'll have to source
+and load the OpenMPI module for every shell you open
+unless you add it within `$HOME/.bashrc`.
