 ## Fedora Server Basics
 
-As stated above, this document outlines the procedures necessary to install and configure Cobbler v3.3.6 on a Fedora 34 host server for local network installations/provisioning through PXE. Additionally, necessary adjustments will be made for security through **selinux** and **firewalld** on the Cobbler server. As such, it is recommended to keep things simple and **limit the number of additional applications installed** to the Cobbler server to **minimize unexpected firewall and selinux complications.**
+As stated above, this document outlines the procedures necessary to install and configure Cobbler v3.3.6 on a Fedora 34 host server for local network installations/provisioning through PXE. Additionally, recommended security measures for the Cobbler server will be detailed towards the end of this guide, including basic **selinux** and **firewalld** configs.

-If Cobbler is to be installed on a Fedora 34 *Server* host, and automatic partitioning was used during initial OS installation, be sure to extend the LVM Logical Volme to a more usable capacity (recommended 95%):
