+The following instructions are for installing Sonarr v3 BETA on CentOS 8.
+
+Please note these were the steps taken by an experienced user.
+
+1. Start by importing the repository’s GPG key and Installing Packages:
+
+```
+yum install epel-release yum-utils -y
+yum config-manager --set-enabled PowerTools
+rpm --import 'http://pool.sks-keyservers.net/pks/lookup?op=get&search=0x3fa7e0328081bff6a14da29aa6a19b38d3d831ef'
+dnf config-manager --add-repo https://download.mono-project.com/repo/centos8-stable.repo
+```
+```
+yum -y install wget git par2cmdline p7zip unrar unzip tar gcc python-feedparser python-configobj python-cheetah python-dbus python-devel libxslt-devel yum-utils  wget mediainfo libzen libmediainfo curl gettext mono-core mono-devel sqlite.x86_64
+```
+
+2. Add a user for Sonarr to use
+
+```
+useradd sonarr -s /sbin/nologin
+```
+
+3. Download, extract and move Sonarr
+
+```
+wget https://download.sonarr.tv/v3/phantom-develop/3.0.4.1023/Sonarr.phantom-develop.3.0.4.1023.linux.tar.gz
+tar -xvf ~/sonarr.phantom-develop.3.0.4.1023.linux.tar.gz -C /opt/
+mv /opt/Sonarr /opt/sonarr
+rm -f Sonarr.phantom-develop.3.0.4.1023.linux.tar.gz
+```
+
+4. Change ownership of the install directory
+
+```
+chown -R sonarr:sonarr /opt/sonarr
+```
+
+5. Create your systemd unit file
+
+```
+tee /etc/systemd/system/sonarr.service << EOF
+[Unit]
+Description=Sonarr Daemon
+After=syslog.target network.target
+[Service]
+User=sonarr
+Group=sonarr
+Type=simple
+ExecStart=/usr/bin/mono /opt/sonarr/Sonarr.exe -nobrowser -data /opt/sonarr
+TimeoutStopSec=20
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+6. Reload the systemd unit files
+
+```
+systemctl daemon-reload
+```
+
+7. Create a firewall rule for Sonarr
+
+```
+tee /etc/firewalld/services/sonarr.xml << EOF
+<service>
+  <short>sonarr</short>
+  <description>Sonarr Download Service</description>
+  <port protocol="tcp" port="8989"/>
+</service>
+EOF
+```
+
+8. Add firewall exceptions if the firewall is enabled
+
+```
+firewall-cmd --reload
+firewall-cmd --permanent --add-service sonarr
+firewall-cmd --reload
+```
+
+9. Enable Sonarr to run on startup, and start!
+
+```
+systemctl enable sonarr.service
+systemctl start sonarr.service
+```
+
+## Troubleshooting:
+
+### Symptom: 
+
+The service has loaded and when browsing to the site it is blank.
+
+Run the following to test for missing mono links.
+
+```
+systemctl stop sonarr
+systemctl start sonarr
+journalctl -xe | grep libMonoPosixHelper.so
+```
+
+If you see a line similar to  
+
+```
+_System.Net.WebException: /usr/lib/libMonoPosixHelper.so ---> System.DllNotFoundException: /usr/lib/libMonoPosixHelper_  
+```
+
+The resolution below will fix that.  
+
+### Resolution:
+
+Run the following command  
+
+```
+ln -s /usr/lib64/libMonoPosixHelper.so /usr/lib/libMonoPosixHelper.so
+```
