+# Building the RPM package
+
+## Install the Prerequisites
+
+### Fedora/Red Hat Enterprise Linux (RHEL)
+```
+sudo dnf -y install git python3-scons gcc-c++ openssl-devel zlib-devel bzip2-devel systemd-devel rpm-build systemd-rpm-macros
+```
+
+On Red Hat Enterprise Linux (RHEL) 8 and clones, you need to first enable the PowerTools repository with `dnf config-manager --set-enabled powertools`. On RHEL 9 and clones, enable the [EPEL repository](https://docs.fedoraproject.org/en-US/epel/) instead.
+
+### openSUSE
+```
+sudo zypper -n in git scons gcc-c++ libopenssl-devel zlib-devel libbz2-devel systemd-devel rpm-build systemd-rpm-macros
+```
+
+## Get the code
+```
+git clone https://github.com/cauldrondevelopmentllc/cbang
+git clone https://github.com/foldingathome/fah-client-bastet
+```
+
+## Build the Folding@home Client
+```
+export CBANG_HOME=$PWD/cbang
+scons -C cbang
+scons -C fah-client-bastet
+scons -C fah-client-bastet package
+```
+
+## Install the package
+The last build step builds the RPM package. Before installing this package it is recommend that you first uninstall any previous Folding@home client software. You can then install the package like this:
+
+### Fedora/Red Hat Enterprise Linux (RHEL)
+```
+sudo dnf install ./fah-client-bastet/fah_client-<version>-1.x86_64.rpm
+```
+
+### openSUSE
+```
+sudo zypper in ./fah-client-bastet/fah_client-<version>-1.x86_64.rpm
+```
+
+Where `<version>` is the software version number. On openSUSE, ignore ("i") when `zypper` complains the package is not signed.
